Well this is difficult since I watch all of them since 2004.
I think BBUK is kind of a role model for the others: always creative, is not afraid of taking risks, its twists are the most copied in the world (even the houses).
There is a whole atmosphere, something you can barely describe: the eye adverts, the pre-BB actually. But sometimes BBUK seems to lose itself by pushing it a bit too far. So can Big Brother UK can stay the leader without making outrageous situations ?

BBUSA could not be more different than BBUK: no public vote, really competitive, airing 3 times a week. This is completely different. The producers do not cast the housemates on the same criteria as BBUK and BBAUS. If you want bitching, backstabbing, game-playing, harsh situations this is the perfect BB but when it comes to have a laugh, it's rubbish. Could BBUSA make it funnier and less staged ?

BBAUS is then again, different than the 2 above. Although it copied so many twists and features from BBUK, when it comes to have new ideas, BBAUS is a rival to BBUK: tasks are sometimes way better, house features and some great drama. But when it comes to the cast, everything goes wrong and makes it as a disaster in the public eye hence the efforts in the new series.
But will those efforts redeem BBAUS from the public eye ?
