I’ve tried Zed, it’s a beautiful editor…it’s just too opinionated. For whatever reason, it doesn’t understand my Deno projects and I content get rid of the red squigglies.
Sublime lives up to its name.
A competitor to Eclipse would be JetBrains IntelliJ or Visual Studio (not Code), both are often considered superior by far, but neither are free.
Eclipse is also a platform for creating applications (RCP/RAP).
I don't understand what practical difference there is between Eclipse/IntelliJ and VSCode with extensions that makes one an IDE and the other not.
