I'm curious, why phpStorm specifically and not IntelliJ or any other jetbrains IDE?
Obviously its php specific features aren't relevant here since we're discussing editors (or development environments) in general.
Personally I find that most IDEs are far too language specific, and I can't possibly invest the time to learn an IDE per language when there's so many languages I regularly need to edit (and probably yet more in the future).
VSCode isn't half bad, as it has plugins for just about everything, but it's still a juggernaut in terms of software size. None of the jetbrains product I've used had decent plugins for all the languages I need.
And of course none of these work over a purely terminal ssh connection, which is a bit of a deal breaker for me.
