Sublime can definitely be that kind of editor, but requires quite a lot of setup in some cases. There is a language server plug-in, which (IMO) is not straight forward to customize or even setup, with very little feedback when something goes wrong (broken LS implementation, or misconfiguration). However, when it does finally work, it's super snappy and clean.
The philosophy of Sublime is almost opposite to VS Code and other IDEs. Instead of everything enabled by default, everything is simple and lightweight by default. Then you add your own things on top.
I mostly see it as analogous to programming, where I too prefer to start simple and add things I control on top and where I understand the whole stack. Compared to picking a huge framework which lets me get started but where I don't understand the hundreds of layers beneath.
Since I use Sublime Text since years, and plan to use it for years to come, I see it as an investment to learn the underlaying functionality and eco system from the ground up. It makes me a better and more productive programmer in the long run.
