What's the difference between The Traitors US and UK versions?

I've watched both versions obsessively. The US version (hosted by Alan Cumming) brings in celebrities and reality TV veterans who are used to game manipulation—making for incredible gameplay. The UK version casts regular people, creating different dynamics. Both versions film in the same stunning Scottish castle. Personally, I think the US version has more explosive entertainment value, while the UK version offers more genuine human moments. The format is identical: Traitors murder at night, roundtable banishments during the day.
