I’ve been keeping a list of alternatives for a while now that I really like:

• Pulsar - An actively developed fork of Atom once Microsoft killed it off. Disclosure: I’m on the Pulsar team so I’m more than a little biased here but if you want to get involved we are always after people who want to contribute and we have a very friendly and active Discord server. First thing we did was re-implement the package backend and migrate it so we were able to keep the thousands and thousands of community packages for download.
• Lite-XL - A really lightweight and fast editor written in C and Lua that is very actively developed. I use this on some less powerful systems.
• Lapce - Another lightweight and very fast editor written in Rust and is in the middle of moving to their own UI framework. Not that extensible at the moment but supports LSP plugins.

Then for terminal based editors I really like Helix which is vim-like but uses a selection -> action model (like Kakoune). I really like it because it requires almost no configuration.

I was using LibreOffice on everything but for some unknown reason it just flat out stopped working on my machine so I installed OnlyOffice and honestly I much prefer it.
