I honestly have no idea why anyone pays for intellij besides a couple of the more niche editors, maybe.
As for general development JetBrains just works. VSCode requires a bunch of extensions made by different independent authors with different standards and it just feels glued together and inconsistent
InteliJ only recently acquired the capability to use Clion plugins for JNI development, something that Eclipse and Netbeans have been capable of for the last 20 years, more or less.
They still don't have an incremental Java compiler, yeah you can use the one from Eclipse, so there is yet another thing that it doesn't do better.
Finally, what is with all that indexing after all these years?
