I mainly work with C#, where I use Visual Studio. I think I mainly changed bindings for expand selection, and go to definition, declaration, implementation (ALT+A/+S/+D). All other bindings work out for me.
Cursor and selection "jumping" with CTRL and SHIFT, and using multiple cursors is a regular occurrence for me. I largely keep using keyboard, but for navigating I do often switch to or combine it with mouse.
When it's not C#, it's often VS Code, or otherwise Notepad++ for non-IDE simple editing. For even simpler quick edits I also use Double Commanders integrated text editor.
I use TortoiseGit, and its diff editor. I sometimes make changes there too. I also occasionally use KDiff or Winmerge.
I think whether it's worth to learn a new one should be determined by 1. what are your pain points/shortcomings, 2. what are the promises or your hopes, and 3. testing it out.
If you explore a promise and quickly find it not useful to you, it may be easy and simple to dismiss a switch without investing more.
