Hello
I have used ST as my primary editor for 5 years now, I have also used VSCode, eclipse and intelliJ (for significant durations) and many other editors (for smaller durations) before this. I also use micro as a lite editor inside the terminal (working through ssh sometimes).
I find the sublime text experience to be… sublime.
I code primarily in python and to a smaller extent in C/C++/CUDA, javascript(+html/css), and golang.
For these languages, I find myself having no regrets.
I also use it for making rst documentation, latex documents (mostly papers), and markdown.
My projects are mainly ML-related, with a slight hint of web-app development and random open source stuff.
I use LSPs heavily, mainly pyright + ruff and copilot sometimes, and the experience is better than you can ever have in vscode (mainly talking about lag and snappines, compared on the same machine).
The git integration with sublime merge is also amazing, and (for complex git ops) I find merge to be orders of magnitude more intuitive than using git solely on the cli or using other apps.
Adding to all this, sublime is perfect even for looking through random files - json, XML, binary - and supports very large files much better than any other editor I’ve seen. (excluding cli/tui editors)
I love that it is so memory efficient that I can have ~7/8 windows open of different projects together, along with a browser (you know how bad the memory situation is there) and not have to worry about memory being hogged like vscode (who thought electron for a text editor is a good idea?). (16GB of ram on a laptop, for details).
The customization is also clearly amazing, and more importantly easy - including making custom plugins!
Take a look at the new Zed editor, whose “talking points” are it’s speed. They compare with sublime, which beats out zed! 
For these reasons, I think sublime is a very competitive choice for a main IDE.
