>they're probably more lightweight anyway

Jetbrains IDEs and lightweight in the same sentence. Notepad++ and Sublime Text are lightweight, Jetbrains IDEs are not...

I literally laughed out loud sitting here at my desk. JetBrains IDEs are many things, but "lightweight" is not one of them. Electron does not have a monopoly on bloat.

But they are Java apps. I use IntelliJ daily (for Scala development) and I'm happy with it, but it doesn't feel lightweight or snappy.

IntelliJ IDEA is easily the worst performing application I use.

I only use it because of the top class Kotlin support (figures, given JetBrains created it).

I end up regularly toggling Power Save mode on and off to reduce how much my CPU gets blown up. That mode turns off code suggestion, auto-imports, and error detection among other pretty core things.
