The UK and US systems share a lot of similarities, which is not surprising considering the history, but UK politics seems better (or rather, less bad) to me? Both Boris and Truss were forced to resign by their own party, whereas the GOP's relationship with Trump is... well, different. Plus in spite of the first-past-the-post system there are actually candidates of alternative parties being voted in, even if we ignore the regional parties like SNP, DUP, etc. The Lib-Dems have a chequered history, but it's better than nothing.
