The only small comparison I have seen for now is this thread between Catto and Pierre Terdiman.

Fluxer has federation on its roadmap

Honestly most good text editors should support LSP these days, which at the very least gives a good IDE. That way you can somewhat decouple the dev environment from the text editor, bar a few exception languages that are harder to work with.

No context aware refactoring ? No thank you !

If you want to start using Vim the way i was intended to be used. You should really learn touch typing. Also, text objects are a pretty big deal IMHO.

LSP protocol

The P in LSP, already stands for protocol :)) “Language Server Protocol”

I’m pretty fine with it. Usually, people who have emojis in their READMEs have put in the time to make it more presentable and readable.

This is originally been forked from a project called “Miru”, but the original dev also ended up making a complete rewrite called “Hayase”, so you should check that too. It is supposedly more performant and has a few new cool features like offline support, episode discussion + other things.
