I think in general you can also just expect that any OS, techy or not, ships with a basic, lightweight text editor. The fact that Windows seems to want to change that is an anti-feature for the entire OS.
Not if you don't use windows, or if you want a more modern looking and less busy interface, or integration with what I consider the best git GUI. I used to use N++ long ago, but after trying ST I realized it just feels clunky.
My entire work brain is in there. Hundreds of tabs none of them were ever saved. I was recently looking for something and found notes I took 2 years ago. I love it but I also get why a lot of people don't.
