One important data point there is Visual Studio Code.
It used to be really popular in 2017 (double the popularity of Atom/Sublime/Webstorm), now it's just eating everyone's lunch (triple the popularity of Sublime/Vim/Webstorm/Atom, almost equal to all of them combined).
Microsoft owns both VS Code and Atom, so probably they're not crying in their beers about that...
Anyway, props to Redmond for a major coup — from webdev pariah to owner of the most popular development platforms in just a couple of years! It took both money and sincere dedication, but they managed to effectively turn around the external perception of Microsoft in this field.
This makes total sense too. I was so hesitant to use something besides Sublime forever, then I tested out Atom and it was slow (this has probably since been improved) and didn't offer much more so the trade off wasn't worth it for looking pretty. Bounced around a few others and then thought I'll try out the VSCode thing, hooked right away and it seems to keep getting better.
Same experience as you. Thought I would always use sublime but my coworkers were so adamant about VSCode that I finally gave it a try. I don't even know that I can point to any single reason for it being better than Sublime -- feels like everything just works a little more seamlessly.
After Atom and Brackets, I almost didn't even give VS Code a try... I'm really glad I did... everything I want in an editor (except maybe binary/hex mode). Integrated terminal and the directory tree are hands down my favorite features, I've seen the directory tree before, but never as good an integrated terminal..
I have 3 editors I regularly use, emacs when I need to edit something in a terminal (eg ssh'ed somewhere), Intellij when I need a full blown IDE (refactoring and debugging), VSCode for everything else.
VSCode seems unstoppable. From my limited understanding, it has very powerful architecture, and it will be most popular editor for .net, Go, Python, Rust in couple of years.

Also Atom is declining sharply.
