I prefer Sublime over VSCode, Atom, etc. but at the end of the day VSCode is free and still very good. Perhaps not quite as fast as Sublime but it also offers other features out of the box which Sublime doesn't so there is a trade off. Is Sublime "better" than VSCode to justify $70? That is something that can only be answered on a case by case basis I think.
Sublime Text has been feature complete (for my liking) for a lot of years now. The only thing I wish it had is an integrated debugger but it's not a deal breaker for me.
I've tried to jump ship to open source alternatives (atom and vscode) but they feel sluggish to me. Most people will be happy with their performance but I've been spoiled by Sublime Text and the slightest delay feels sluggish to me.
There was a time when that was the case, but for quite a while now we've been seeing frequent releases.
The way I think about it is: How many hours of time does Sublime save me per year relative to another editor. Even just 1 hour makes it worth it.
