hmmm. I'm a regular emacs user w/ Doom configuration on top of emacs. I love emacs and I use it exclusively, however it does crash sometimes for me. It's enough to notice, but not enough for me to care.
As a fellow doom user, Emacs became lot more stable (and faster) after disabling bunch of default doom packages and modules. In its default config, doom really is intended for use on semi-modern processors with SSDs.That fancy modeline et al come at a cost.
emacs really is just an interpreter for emacs lisp. it does whatever you program it to do. it happens to come pre-programmed as a text editor from the "factory".
The beauty of emacs is how easy it is to modify it. Lisp is the easiest syntax to learn, emacs hides nothing from the user, and the user can override or add whatever they wish. It really is a proper example of free and open software. To add to this, it's all very well documented, and everything you need to develop (for) emacs is in emacs itself.
