Primarily IntelliJ IDEs.

I'm using IDEA for Rust & Kotlin, PHPStorm, Datagrip (DB), and sometimes PyCharm CE.

IDEs can feel a bit dirty with how heavy they are, and the lack of customization/control. But at the end of the day there's just nothing that can measure up against IntelliJ's inspections, integrations and project indexing.

My ideal product would be one universal IntelliJ IDE, but combined with the openness of VSCode/Atom, having everything transparently configurable through stylesheets and scripts.

As an editor though.... I use Vim for LaTeX, Markdown, plain text and Haskell code... but not so much for other programming languages.

Vim was my first editor when I moved from C64 to PC development 25 years ago, and while you get used to balancing keybind vimgolfing with being actually productive, i've always found maintaining plugins and profiles too cumbersome -- the reality is that Vim is an awesome TEXT editor, but it's really awful as a CODE editor out of the box.

When you want to try out a new programming language, you don't want to have to mess around with your Vimrc and Vundle and YCM for half a day just so you can comfortably write "Hello World" in Rust or Elixir... you just want to click one install button, press F10 to compile and see if it flies.

Oh, and I use Xed a lot for quickly editing files... because it's the default GUI editor on Mint desktops, and it's quite good at being a basic notepad.
