I guess it depends what you mean by "good".
The set-up is similar in some ways - both our countries have a highly adversarial system dominated by two parties. But the American system seems to accommodate a greater diversity of opinion within each party, whereas in the British system strict obedience to the party line is the norm. Or at least it was until the recent Brexit turmoil, which has seen the Conservative Party splitting into at least three factions.
My opinion of the two main parties has been deteriorating year on year, but if right now if I had a gun to my head and a ballot paper in front of me I would choose Labour as the better of two undesirables.
As for Trumpicans, I don't think there are many of them in the Parliamentary Conservative Party, in fact if such people exist they would be more likely to support the UK Independence Party.
