xPeeps seems to have a good platform, a clean interface and a better support for HD webcams. But they don't have traffic.
From a model who recently tried xPeeps:
Okay, the traffic on xpeeps is absolutely ridiculous. I don't think I'll cam there again.
I was the only model online and had between 7 and 13 people in my room.
This was tweeted by her, but I'm leaving out her name because I don't know if she wants to get into the debate.
She is a quite attractive model who likes to interact with members. She has webcam, lighting, audio... everything set up perfectly. So, I doubt she was the problem.
You meant, MyGirlFund, right? I don't know much about them.
And if you haven't talked to Amber to get your model status yet:
How to get model status. Maybe there are more threads about these sites in the Models Only section.
