I've got quite a few BumGenius V2 one-size pocket nappies... I find the fit and absorbancy to be brilliant. After about 9 months of use they are looking a bit ratty (a couple have shot leg elastics now too), I feel they lose the 'new' look pretty quickly.

Despite these couple of niggles (which you get in a few brands) I've found them to be excellent value for money and they do a great job.
