I used to use JED when I was stuck on DOS. I was surprised to find out that it's still being maintained on github and the author recently made a commit to improve vms (!) support. https://www.jedsoft.org/jed/
jed starts very fast and has much lower memory usage, so it is well suited for quick edits of configuration files and scripts and other workflows, where you start your editor in your shell, instead of the other way around.
emacs (through packages) can be turned into a custom IDE for a lot of languages, but takes more disk space and uses more RAM.
I used to use jed all the time, many years ago. But a package for it isn't available for the os (opensuse) I'm using these days and I couldn't get past the configure script when I tried building it myself. Maybe I should try again.
OpenSuse is such a great base OS, everything is cohesive, but I really wish it had more packages. Flatpak covers most of its shortcomings but sometimes you need something a bit unusual or that does not pair well with Flapak.
I am currently using Fedora mostly because of this.
