After 20 years of vim I decided to try out Helix back in Feb and never looked back, so I guess I can chime in here.

Sure, it took a few days (maybe weeks?) of feeling uncomfortable, but unlike vim, Helix is very approachable. I think you have to be okay with a certain level of feeling uncomfortable if you want to do or learn anything new though. If learning a new editor isn't your thing, then don't. :)

I get this same question a lot when people realize that I use Dvorak layout. Sure, yes, it took time to learn. But I was curious if there was something better for me on the other side. It seemed plausible that there would be, so I gave it a shot. In both cases I have been happy with my investment.
