I took the same journey. I switched from Sublime Text to VSCode and stuck with VSCode for months, and depending on project du jour I've done this a couple of times. For me its mostly speed and a number of small, but frequently encountered, quality of life issues that keep me coming back to Sublime Text. Some of the small differences around cursor/multi-cursor management never stop irritating me in VSCode compared to ST. Also, I do a lot of PostgreSQL related stuff and I've yet to find a syntax highlighter that's 1) just syntax highlighting; and 2) able to handle things like dollar quoting well for VSCode where in Sublime Text I've had such highlighting for years.

Sure it doesn't see frequent updates... but so what? That might well be a strength since some kinds of changes can be low value & highly disorienting. The plug in eco-system isn't as broad as that for VSCode, but unsurprisingly there's more cruft there, too.

Ultimately your mileage will vary based on your preferences, but I'll stick with Sublime Text until there's something really more compelling.
