5 was very good, but 6 just aces it in every department. The house was designed nicer, the factions and arguments were more unpredictable (5 just had the 'jungle cats' vs. 'lipgloss bitches', whereas 6 had Craig/Vanessa/Makosi to begin with and then he joined Anthony's lot and then Kemal, Science and Roberto hated just about everyone).

I think BB5 had more one-off "moments" that make it perhaps more memorable - fight night, Stuart's surprise eviction, the bedsit - but BB6 was a continuing stewpot of drama and entertainment.

But really, it comes down to the housemates.

Craig, Makosi, Derek, Kemal, Science, Roberto, Mary, Kinga... even the awful people like Saskia, Maxwell and Lesley...

against who exactly? Victor, Nadia, Jason and Michelle were the only really interesting ones.
