I used emacs for a few years also basically consistently running and moved off pieces of my other software to emacs functions but then I piece by piece figured out that while it does and can do a lot, it kinda does nothing properly or at least, let's say, particularity well. I'm of course mostly talking about the available packages. While it's true you can extend it programatically and I did get along with elisp somewhat (although I never developed a love for it, and I tried) in practice you're just not going to fork and rewrite packages. It's just not a thing that happens for most people. I also tried vim for several years, and came to a similar conclusion like with emacs, although it did seem more polished overall if you could resist to lurk under the hood and avoid the insanity that's waiting for you there in the form of vimscript. I then used vis for a while, which is basically vim with some features of Plan 9s sam in it and lua. Liked it more than vim, but again didn't do a whole lot with it.
Eventually I went over to ne which is a tiny, feature-clean and efficient text editor very similar to Amigas TurboText which has the feature of letting me pipe text blocks through external programs and insert their output and let me script hotkeys, the top-down menu and a few simple macros in the purest form of the sense. (no scripting language really) I decided that's all I really need and want from a text editor. I then made a few small patches to it to fix some annoyances which was only comfortably possible because it is as small as it is. If I need external programs to do things to text, I can write them in whatever language in whatever way and use that pipe feature. It's better if a program does one thing well instead of many things "kind of". Emacs is a lot of the latter.
