I was on sublime text for the last 12 years. I made the switch to helix and although I missed some features, it's been a great change. I never could get into the vim bindings, but helix's defaults are great and I don't need to go plugin hunting in order to make the editor functional.

There's missing features I really want, but they'll be added eventually. Git blame in line, some scripting support, better find-replace across a project and not just the opened buffers.

Just give it a try for a week or two straight. No using your other editors. Cold turkey. You'll be surprised at how quickly you'll relearn. It took me about three weeks using it full time to get decent. The first day or so were brutal.
