> Intellij git integration in comparison, in my opinion, it's barely usable and generally counter intuitive.

Disagree. I use it all the time. It's sooo nice to have the different changelists. Easy to make changes that I don't want to accidentally commit by putting them on a different changelist (like pointing to a different database). And it can be split even in the same file, much more easily to commit parts like this than using git -p.

> BTW the java plugin bundle for VSCode replicates 95% of the features of Intellij,

If you only look at the textual java code, perhaps. But it lacks the awareness of the rest of the java ecosystem that Intellij provides.
