IntelliJ is expensive if you want languages not covered by the free edition (like JavaScript), though, and even if you pay for it some things are frustratingly distinct such as if you have a Java/C++ app you need two different "IDEs" (CLion + IntelliJ), and you need to then juggle between those windows. Android Studio is able to work with both even though IntelliJ Ultimate isn't (why, Jetbrains, why!?), but getting Android Studio to work on non-Android things isn't the nicest of experiences.
I'd be more willing to pay for the quality if a nice, unified experience was the result, but it annoyingly isn't. To say nothing of the lack of support for things like Rust.
That's what this new generation of IDEs is exciting to me - the unified language server standards. Let the compilers handle understanding the code which is what they are best at. Especially if it helps make IDEs less tied to the build system in general (no, CLion, I don't want to use CMake)
