I don't think Peyton is that good. I've never seen a gimmick that isn't annoying screechy Aussie from her yet
She hasn't proven she has anything other than that.
I like Bianca a lot though. I wasn't keen at first, but she's grown on me a lot.
Wrestlers don't necessarily need to be capable of a variety of gimmicks to be successful. In fact, if you're good enough at one gimmick, that might be all you ever need to play. I'm not saying that Peyton is good enough in her current role that she can coast off of it for the her entire career but, well, a lot of people do love The IIconics, so maybe she is.
But speaking of which, I personally would rather The IIconcis stay together as long as possible. I think more than either one of them being particularly funny, it's their chemistry with one another that makes the gimmick work. But then again, people probably said the same about Edge and Christian.
As far as Bianca goes... yeah. She just screams future star. I remember watching her first significant match on NXT and being impressed by her poise and confidence. It felt like she was meant to be doing this. She still has some developing to do, but she easily has all the raw talent in the world.
