UK networks: O2 or 3

[docwil]

My contract phone is nearing it's final month and was wondering whether to stick with O2 or move to a better deal with 3 mobile (or any others if that helps?)

I was looking here to compare contracts: http://www.moneysupermarket.com/Mobi...s/default.aspx and I like the idea of the 3 contracts on offer, I'm meant to be paying 30 a month with o2 but they don't offer nearly enough texts so i keep going over.

I don't call that much so i'm just wondering if some sort of mixed contract from 3 would be better. What does everyone think? anyone been with or changed to 3? ar etheir customer services any good?
