I used neovim but recently switched to helix and highly recommend it. If you haven’t tried nvim yet, give helix a try before deciding. A good way to compare is do the tutorial of each and see which you like more nvim +Tutor and hx --tutor (orhelix --tutor).
If you’re a current vim user the helix keybindings are only a small learning curve after the tutorial, and feel a lot smoother imo
