I'm probably one of those weirdos who use VSCode, Kate, Nano, and sometimes KWrite all in their different niches.

I do most of my programming work in VSCode, but most of my shell scripting in Kate. When I edit configuration files, I'm usually using the command line and thus use Nano (sorry, I'm too stupid to use either Emacs nor Vim, let alone Vi). When I'm just looking at text files (or doing a quick edit) via my file manager, I use KWrite. With the exception of VSCode, they're all provided in my installation by default.

Having said that, trying out different editors will enable you to pick the editor that better fits your requirements. Kate is too powerful for what I use it for, but since it's already there, the additional features are nice to have. I actually had to explore a bit before I‌ settled on VSCode for my programming work, and while there's probably one that better fits my needs, my workflow has already adapted to working with what I currently have.
