I'm kinda conflicted! Right now as in this season I think BBUK is better but it depends on the cast. Of course the shows are very different but I think both shows could and should learn from the other. I wish there was a vocal Big Brother in the US show. I think the audience would love it. BBUS seasons 2,3,5,6,7,10 all great to me. Especially seasons 2,3, 7 & 10 BBUK seasons 2, 3,5, 6, 7 and this season are all worth a watch. If I had to choose one version I would have to choose the UK version as I think the whole experience is tougher and with a house mate like Aaron I think the show is going in the right direction.
