OpenSuse Leap is my favourite distro.
Occasionally I try out others, some I really like, but I always end up back on leap.
When I was about 9 my family went to the jorvik viking center in York. They had a ride thingy where you could be driven around a realistic viking settlement and whatever the fuck they used to make the realistic smells of smelly vikings and pig shit really fucked me up. No one else was that bothered but I couldn't eat properly for days.
I'm guessing whatever chemical they used really didn't sit well with me. It must have had a pretty extreme effect because that was 31 years ago and it was the first thing that popped in my mind when I saw this question.
Org mode changed my fucking life! I looked into using emacs as a simple markdown editor when I was doing a creative writing course and discovered org mode. 4 years later and I never leave emacs, everything is done through emacs and org mode. I even use it as my window manager (exwm). I bought an old chromebook to turn into an emacs machine and it's so good. It's an operating system and I don't like using a computer without it.
Some things for you to look into that I now can't live without:
Elfeed
Org-capture and capture templates
Dired
EXWM
Syncthing (not a part of emacs but means I don't have to use closed source cloud backups)
I passionately love emacs. At first I thought all they shortcuts and keybindings were a bit insane but they are second nature to me at this point. Emacs has also saved me lots of money that I would have spent on silly writing apps and aids.
