I used Sublime Text since ST2, and bought into ST3. It just felt stale compared to Visual Studio or any JetBrains IDE. I loved the speed, but at least back when I was using it, LSP wasn't as big and so I didn't have that at my fingertips.

With Zed all the high quality features are OOTB. For example, with Python they run some high quality linters out of the box, I don't even have to think about setting anything up, I don't even thing I have installed a single plugin for Zed outside of themes. It's a very batteries included text editor.

Not the OP, but for me ST can't be beat in terms of how easy it is to write a plugin. It uses Python (Zed is Rust). Plugins generally auto-reloads. If extensibility is important to you, ST is still the way to go.

sublime text is a joke with regards to LSP

It doesn't even respect local project dependencies

Plus the whole "holy than thou" attitude of python devs in general just sucks tbh

Python isn't as great as you think it is.
