I've switched to vim on a whim few months ago, and it still is a pretty fun and satisfying experience. I couldn't get LazyVim to properly work on our Unity project, since the LSP can't handle the hundreds of projects it generates, but IdeaVim in Rider works pretty much the same, as far as the movements are considered.
However, the important thing is that I said fun and satisfying, not faster and efficient. I still make mistakes, I have to look into a keybind reference sheet every time I want to do something I'm sure has to have a special keybind but I've forgotten which one it is, but once you do that it feels good.
Slowly but surely learning new stuff, getting the hang of some motions you use often, not having to reach for your mouse, all of that feels good. It's still no way near the speed or efficiency of me just clicking the damn mouse, instead of fumbling around with VIM modes, undoing random actions because I missed one important key and now half of my text is gone, or just remembering that your clipboards get overridden by almost any action unless you do it differently.
So, if you want to get efficient and quicker in your programming, I highly recommend checking the keybind section of your IDE, and learning the few important keybinds it has, such as jump to next function/next parameter, search symbols, and the like. That will make you more efficient.
If, on the other hand, you want your editing to be a skill you can slowly continue mastering, eventually (after years of use) min-maxing, but always having some cool new things to learn that will feel good, them vim is pretty nice for that.
Just don't expect it will make you faster or more efficient.

The issue isn't whether you can get a good results or not. The issue is the skills you are outsourcing to a proprietary tool, skills that you will never learn or forget. Getting information out of documentation, designing an architecture, understanding and replicating an algorithm, etc.
You will eventually start struggling with critical thinking, there are already studies about that.
Of course, if you use it in moderation and don't rely on LLMs too much, you should be ok.
But how did that work for everyone with short-form content and social networks in the last ten years? How is your attention span doing? Surely we all have managed to take short-form content in moderation, since we knew the risks to our attention span, right?
