It's sweet that you want to help models but lets be real here, unless you're actually a webcam dev. you're not going to have as much background knowledge about how they actually go when compared to the resources available that are industry peer/mentor written.
For a start, you've linked a bunch of youtube reviews which the models you have posted in the idea of helping could have found by just googling "what's the best webcam for streaming".
There are also private groups, forums, chats, discord servers, etc... where models can converse about their experiences and ask questions to each other.
Even on here there are extensive private threads about what works for which purpose...cams, toys, mics, computers, software, etc...
If someone doesn't use their equipment the way I do, they would have an entirely different setup, and mine wouldn't work for them at all.
yes bluey understand that. when bluey talks with models, bluey discusses in-depth about webcams with them and before bluey even suggests they go for a better webcam for image quality, if they're using something like a Brio, if they don't have it set up optimally, bluey makes sure that's done before they decide they're not wanting to use the Brio strictly because of how it looks, because majority of the time that bluey's came across models with the Brio that didn't like how it looked, it wasn't necessarily because it was bad, it was because they didn't have everything set up properly, but with that considered, it's still not better image-wise than any of the webcams bluey's listed here.
also, you don't necessarily need to be a webcam developer to know which webcams are the best image-quality wise. in fact, developers rarely both critique and write comparisons and this is well known among professionals especially, so bluey not sure where that came from with the industry peer/mentor written webcam developer statement. also, all of those webcams have objectively superior software to the Brio, which is also a fact and doesn't require being a webcam developer to know.
as bluey mentioned but you might not have seen it, bluey is in a discord full of Mac, Windows and Linux coders, professional photographers/video editors, tech writers/educators, audio engineers etc (one of which professionally covered the Brio on its launch). this is partly why bluey refuses payment, because all bluey is doing, is going to the verified professionals and essentially getting the information for the models bluey have helped, so they don't have to, but this is also a field of interest that bluey is pursuing.
as for "what's the best webcam for streaming", navigating information like that is subjective, you might not even find some of these webcams because it requires people bothering to make the blog posts in the first place, which happens to actually most often be on YouTube, not google. best webcam for streaming is an extremely saturated google search, so, in your argument sake, this is also not always professionals, whereas some of the people who are reviewing and verifying their performance on YouTube, are. bluey promise if these 4 webcams came up, and you also took whichever other webcams are in the top webcams list for streaming, what you see on google will almost never align with any professional photographer/video editor and there's a very good reason for that, but that's in reference to image quality. outside of image quality, then yes there are other variables people will want to consider, but as bluey has had to reiterate now multiple times, that's something bluey understands absolutely perfectly, which is why it was not a variable in writing this thread because that's not what the thread was about.
this thread was made strictly for 4 reasons and 4 reasons only.
1. google is highly saturated with blogs showing Brio as the best webcam you can possibly get even for image quality, that's nothing but wrong, period, and the videos above will not only prove that, but so will going to any professional photographer/video editor, bluey promise not a single professional in that regard will say the Brio. blogs even have webcams as #1 that are not better than the Brio in performance and they're like $20 - $30 more.
2. among the many models bluey's helped, they ask what the best webcam is in terms of quality (image quality), and so far, every single model bluey asked that had the Brio, they bought it because of reason 1.
3. Conference webcams. bluey has come across about 8 models with Conference webcams and that's 8 too many, these things are insanely expensive for the quality you're getting with image, they will be anywhere from almost $1,000 to over $3,000, at that point, should've literally got the Brio at the very least.
4. as bluey have stated now quite a few times, there have been models that didn't want to get into the whole potential headache of DSLR/Mirrorless and just want a webcam, but they want something that looks better than the Brio either when they next upgrade or just immediately to replace it with.
so bluey will clarify again, this post has literally nothing to do whatsoever with the Brio to any capacity, other than dethroning the delusion surrounding the idea that the Brio is the best webcam for its image quality and that's it. if people want to talk about how great the Brio or other webcams have been for them, bluey's all for it, but for those that have done so, don't start pulling out bullshit ideologies that aren't even statistical, that factually do not apply to every single model that cams and then waste time spouting that dishonestly bias ideology on a thread when that specific ideology was clarified to not have anything to do with the thread the way they thought it did. that's an error of bluey not having edited/not being allowed to edit the post to specify the best looking webcams you can buy and that these chosen best webcams pertain to image quality and software.
to clarify otherwise with Lilly's supposed claim that bluey's in opposition of people discussing about the Brio, just because it's not relevant to the thread, doesn't mean bluey is in opposition. not one time in this post anywhere has bluey called or insinuated the Brio was bad. and just because it isn't as good as the others, doesn't mean it's garbage and it's delusional to assume that's insinuated just because the simple concept of something being "better" for something particular.
So as bluey mentioned, this thread was meant to pertain to the image quality of webcams or simply best looking webcams you can buy and bluey can't edit the post because the forum does not allow you to, after something like 15 minutes has exceeded from the time the post was made, thus bluey understand why people mentioned certain things about the Brio that doesn't pertain to image quality, but bluey had clarified this and that still continued, so obviously people just want to keep arguing for the sake of arguing and that's when the unnecessary bias of pretending like they know every single model in the world that cams just because they're "in the business". that's not a statement that's made in reference of trying to be helpful, that's plainly arrogant, then bluey gets called the arrogant one, which makes no sense since arrogance is constituted by the individual's
exaggeration of their importance/capabilities. there's literally nothing whatsoever that bluey wrote that's arrogant, but trying to pretend like they know what every single model wants in terms of preference when that's obviously not the case, then simultaneously trying to validate that prideful lie with something such as "I'm also a cam model", THAT is arrogance by definition.
The fact of the matter is, bluey's helped many models where these such generalizations did not apply to them, where having known about these webcams beforehand would've saved them money whereas the whatever else they were using, became either a back-up now or simply they want to sell it because they have no intention of using it because
they (not you, as in others) don't like how it looks image quality-wise.
