When Goland launched it wasn't that much different from IntelliJ IDEA with the Go plugin. In the intervening years it has come to feel like a significantly better product than that combination.
This is why I am happy to see RustRover - it's very likely the significantly better product is actually similar for the Go plugin. Once they release an IDE, it seems development picks up and things get a lot better quicker.
I have used clion with rust plugin and while it's better than nothing, it's generally been pretty spotty on all the features, completion, marking errors, refactoring. I'm looking forward to RustRover "pulling a GoLand" by bringing a proper IDE experience to rust.
Not much actually, but for me it’s default settings of Goland vs “you need to setup some small things, plugins and shortcuts in Intellij IDEA Ultimate to work with Go effectively”. Ultimate is also a bit slower if you don’t disable a ton of Java plugins. But if you don’t need Java and disable it anyway, why not to use more streamlined and lightweight Goland?
the go plugin that existed at the time of goland creation and what exists today are very very different things.
the go plugin back then was very simple. The fact that you get most of the goland experience in idea ultmate today is because they are investing into the go ecosystem as an independent profit making endeavor in and of itself, not simply a small value add.
