I think my least favourite series was 6, the only person I really liked was Tim Vine, the others were ok but dont think the show was that funny. The latest 2 series I cant say I've loved them as much as most others. Maybe it's just a covid/studio distancing thing, as there has been no discernable difference since they moved to Channel 4.
There was an American version that I've never seen. It had Alex Horne in it but no Greg, so it's no surprise it only lasted one series.
Seeing James Acaster getting angry is brilliant TV, hes great. Out of all the guests theres only one person I genuinely disliked and that was Ian Stirling, although to be fair to him, even he didnt like how he came across on the team tasks.
