I know, I will get a lot of downvotes, but as someone who using emacs for 5 years and switched from vim. And also as someone who have friends who are using vim/nvim and tried emacs. I have to say, if you are into unix philosophy (writing small programs which solve one problem really good), you should be at least prepared - emacs is anything but unix philosophy. It’s about having the whole universe on your laptop just to play tetris. Which is obviously not about clean small solutions. And as I noticed, there two groups of hardcore devs - those who go vi way and those who go emacs way. So, if you want to try, just run emacs and use builtin documentation. It’s great. But if you will feel that it is not your thing, I suggest trying nvim. Because it is vim which gets some emacs benefits (like having a normal language to write configs).
