Neither applies to the problem at hand. The problem at hand, as others have pointed out, is about switching tools.
I switched from decades of using emacs because stretching for key chords started to hurt my hand. I went to vi. It was a pain for a few days because my hand-brain had memorized emacs. After about a week, I was able to do simple things without errors. A few weeks after that, it started to be fun and I got to the point where I could work as easily as I had in emacs. And then, owing to plugins, I started to get more productive.
Here's my advice for folks switching to vi: get a medium-sized postit note and write a couple of common key sequences on it. Add new sequences as you need them, but don't bother for things that you only do once in a while. After a few days you'll need to tape the note down, because you have been removing it repeatedly to add new things. Use tape to hold it down. After a few weeks you won't need the postit note. But spend an hour or so each week reading up (or viewing videos) about vim things -- not things you need, but things that interest you. This hour is your long-term investment.
As for configuration, I wasted a heck of a lot of time on that (in both vim and emacs). A few months ago I switched to lunarvim, which is a neovim that comes in a state that already has a ton of things I want. That's my advice for anyone switching to vim ... go past it to neovim, perhaps trying lunarvim as your variant. (There are other variants, and I've not explored them. I did some web searching and it seemed as though lunarvim was well regarded. All I can tell you is that I feel no need to switch.)
