I use an LSP and every IDE feature in intelliJ for typescript, Java, and anything else well-supported by jetbrains... except Ruby.
For me, Ruby's standard library tends to use names for things I would guess first, and the way people build things in Ruby feels natural to me. Any sort of LSP feature is nice obviously since it's never in the way, but when I end up trying Solargraph or RubyMine I end up noticing I'm just not paying much attention to it. The only places where I end up reaching for it is mass refactoring, like big renames... which are tough in things like Rails projects where files need to be renamed and pluralization matters.
So for me, it's the ergonomics of the language. That's probably mostly related to hours spent with it of course, but I think everyone has some specific environment/language/style that lets them compress the current state of what they're working on in their head better than anything else.
