I started with emacs. I love the buffer / windowing system and the on-the-fly macros. Also being able to do everything with the keyboard.

But the time spent getting multimode up or good autocomplete when you can simply fire up something like jetbrains IDE, having most of your ecosystem tools integrated the second you launch it makes the decision to switch easy.

Also, dev machine tend to have a lot of resource nowadays so the RAM hungry IDEs are not a problem.
