Only having watched a fairly small amount of either, I am only basing my choice on first impressions. 1st of all I watched the first 3 or so episodes of BB US . Every thing seemed fine at 1st . But after two hours of the typical US approach to TV shows, I couldn't take any more. Its so corny, with the dramatised back round noise and over the top presenter . So I knocked that on the head and went In search of BB OZ. I found it a lot harder to find for some reason, although the sites had links to show a certain episode , a lot of them were out of date. So in the end I compromised and started watching BB OZ from episode 59 I think... I am pleased to say, I found it to be a lot more entertaining and a lot less corny. Even though I'm sure there eviction presenter is trying to mimic Devina.(they do look similar) But all in all I though it was great and would recommend it to any BB UK fan
