Whichever Jetbrains IDE is appropriate. I fell in love with Rider and wound up paying for their all-inclusive license. I've since made heavy use of Webstorm, CLion, and Datagrip professionally and personally.

Visual Studio Code. It has great defaults out of the box, is highly customizable and extensible, has near universal support for every programming language, and runs reasonably fast on my machines.

NeoVim. Endlessly customizable, quick to start, and can offer whatever niche feature you’d like. Did I say it was endlessly customizable?

When I first started programming a few years ago, I used Python's default IDLE. After a few months of that I switched to Atom (RIP), and shortly after moved to VS Code. I've stuck with VS Code since.

IntelliJ IDEA

VS Code, but may switch to VSCodium or Neovim eventually.

Emacs

GNU Emacs

JetBrains for everything

Neovim or Jetbrains depending on the project and my mood.

JetBrains IDE all the way. Mostly Intellij Idea, WebStorm, CLion (for Rust) and PhpStorm. Once in a while Visual Studio Code for a quick text file edit.

NeoVim.

Helix 🌚

I have a JetBrains All Product Pack license, so they are always my first choice. I tried VSCode and vim, but they require so much work to get to a useable state whereas a true IDE can be used right away. I want to code and not turn fiddling with my editor into a hobby. I do use VSCode and vim, but only for editing text. And I use vim key bindings everywhere.

I just use a stack of cards and a knitting needle.

IntelliJ. With Vim-keybinding.

Emacs with doomemacs config. Really fast and very neat for what I do.

Neovim. Nothing interesting, but it gets the job done way better than anything else I tried. I had my own config until a week ago, when I switched to nvchad because of my unwillingness to port my config to lazy.nvim plugin manager.

VSCodium.

Visual Studio and VS Code.

Vim for light work, emacs when I need more ide features. I program mostly in fortran, c , c++, and bash on remote servers.

Anything that is not Android Studio.

Vi. Not even Vim. Just whatever vi is preinstalled on Arch Linux.

IDE's and I... don't get along.

Emacs built with Nix. I host my configuration on GitHub.

Intellij.

I use Emacs. Doom Emacs to be exact :)

Recently started using neovim with LazyVim and I'm enjoying it.

Intellij for backend, VS Code for front end

Visual Studio professional. It’s so slow though. Would love to use anything else, but am locked down due to work.

Notepad++ , nano if that counts lol

I mostly code in Python and for that I use PyCharm. For everything else I use VS Code.

Pycharm

Visual Studio for work (c#), Pycharm when I need to do Python.

VSCode for Python and RStudio for R.

VSCode usually, Xcode when working with Apple platforms specifically

what, no love for CodeLite when working on smaller projects?

For Python, VS Code and Jupyter Lab. I used Sublime Text 3 previously but have found VS Code to be easier to set up and better supported over time. I do miss how fast and lightweight Sublime is this compared to VS Code though so I still use ST4 as a general text editor.

For Excel VBA (ugh), pretty much have to use the built in one as there doesn’t seem to be any alternative.

It keeps changing with the job. I've used Eclipse a whole bunch of times for Java projects, IntelliJ a couple of times. Pycharm for Python. Vim for Bash and a bunch of other stuff. QT Creator for some C++ with the QT framework. Now it's mostly VSCode.
