I just tried Zed and it is definitely really pleasant to use. I'd need at least a Java LSP to use it for real (and preferably general LSP support so I can code in my own programming languages with it) but I can see a lot of promise. If they ship a Linux release so I could use it on my desktop too they could win me over from Sublime Text/IntelliJ.
About 70% of the programming I'm doing right now is in my own language. But like, my full time work is programming language research so I accept that's an uncommon use-case.
