Favorite universal system or paradigms?

Been reading more systems as of late, in part because I want to run a game and part just out of curiosity.

Generic/universal systems have been interesting to me in particular since it means a core set of rules you include or exclude based on the vibes you're going for rather than having to hunt for something specific or trying to hack something to make it fit. There's a bunch of them though, each doing interesting things so it makes choosing difficult.

I wanted to know which generic system a la GURPS, BRP, Cypher, etc or paradigm (like pbta) do you like and why is it your favorite? What kind of games do you like running the most with universal systems? Is it a slight twist on typical scenarios or do you go crazy with it?
