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

Emacs

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

GNU Emacs

Neovim or Jetbrains depending on the project and my mood.

JetBrains for everything

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.

Helix 🌚

NeoVim.

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.

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.

VSCodium.

Intellij.

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

I use Emacs. Doom Emacs to be exact :)

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

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

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

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

Intellij for backend, VS Code for front end

Pycharm

Visual Studio and VS Code.

Geany

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

VSCode usually, Xcode when working with Apple platforms specifically

VSCode for Python and RStudio for R.

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

Notepad++ , nano if that counts lol

These days I write Lisp code using the Medley Interlisp development environment. It's a vintage but amazingly capable environment that's being revived and modernized.

Visual Studio

Notepad++ for non ide stuff like data files and scripts.

Occasionally Visual Studio Code. For mass text replace and some other tooling / envs.

VSCode is the best code editor around, the plugin ecosystem is phenomenal, copilot specifically has been the biggest boost to my output in 15 years of development.

Unfortunately it doesn't do everything, I got stuck with some really old legacy software and have to hop into the vb6 ide, code::blocks, and very rarely visual studio.

Multi-cursor wizardry is absolutely life changing
