Except Eclipse does C++ better than CLion and it's $250 cheaper. The only real advantage JetBrains has here is consistency with their other products, but then they ruined that by putting it in its own standalone product. So you can't have, say, a Python/Java/Kotlin project with a C++ extension library in a single IDE window, at least not if you're invested in JetBrains technology.

Whereas that would work fine in vscode, Eclipse, Atom-IDE probably once it gets a C++ language server plugin which LLVM is working on, etc... Competition is good. IntelliJ is far from complete. That's really all I'm getting at. IntelliJ is not the pinacle, superior end-all-be-all IDE that some were saying here. It maybe is if you're in their primary supported set of languages. But it's not if you're at all on the fringes of what JetBrains supports (not that I'd necessarily call C++ a "fringe", either, but whatever)
