I don't think 6x7 is bad but at uni when I have the choice between a Mamiya RB67 for a project or the Hasselblad 500cm I go for the Hasselblad (and I own a Mamiya C3 which is a truly brilliant camera). I like composing better with the 6x6, however i'd still love the RB67 if I had the money to get one. Also the fight between 6x7 or 6x6 is a debate that constantly breaks out at uni.
