My needs are very basic, so I didn't give Sublime much of a look. I specifically wanted something macOS native, and CotEditor was one of the few, possibly the only, that supports Versions. It does everything I need it to.

I’m going to give it a try tomorrow

I tried it briefly but found it too basic. The lack of tabs was the main problem.

Cot Editor has loads of tabs. Also supports ligatures and OpenType features.
