Having seen two seasons of US, 2 of UK and one of AU (season 2 isn't on Peacock yet, but I've read about the result and ....WOW) I think I prefer the US version because I don't feel so bad about celebrities being hoodwinked and backstabbed. The casts made up of regular people were more creative in their treachery, but I cared more about the folks who lost. And as for hosts: Alan Cumming > Claire Winkleman > Rodger Corser.
I think I read somewhere that the Australian version was canceled for lack of ratings, right after season two aired. Go figure.
