There are times when I think this, because the stuff I play is progressive metal, so you have to be good at it. However, everyone in the band always seems to look to me as a guide in a sense. Why is that? Because I formed the band, rather than looked for one.
It meant no auditions, and the stuff we play is down the alley I've always wanted to go down.
This could be a good route for you, that way, you play how you feel rather than what you are told.
To be honest though, its probably just you being too hard on yourself, I usually am, as every band I've been in has told me I'm a great guitarist, I just never quite feel like I'm where I wanna be. Don't let things like that stop you enjoying yourself, the best thing I've ever done for my playing was join/form bands, it teaches you how to be tight, to be selective with what you play, how everything works together, rather than just being a bedroom w**ker :)
