I don't feel the need for Sublime to step it up, because nothing is on their level yet. I tried Zed and went back to Sublime pretty quickly as it is by default lighter weight (the main Zed process is fine but it automatically runs a bunch of nodejs bloat) and doesn't have a bunch of useless AI crap. You can turn those things off in Zed (kudos to them for that at least), but I prefer to stick with an editor that doesn't need to be tweaked to get rid of bloat.
