Intellij has a ton of features but it's pretty heavyweight because of it; I'd like a properly built native IDE with user experience speed at the forefront. That's what I loved about Sublime Text. But I also like an IDE for all the help it gives me, things that the alternative editors don't do yet.
I've used VS Code for a while as well, it's faster than Atom at least but it's still web technology which feels like a TON of overhead that no amount of hardware can compensate for.
I've heard of Nova, but apparently I installed it and forgot to actually work with the trial so I have no clue how well it works. I also doubt it works for my particular needs, which intellij doesn't have a problem with (old codebase with >10K LOC files of php 5.2 code and tons of bad JS, new codebase with Go and Typescript / React).
