This is myself as well, enjoying the extremes. Having all the whiz-bang guidance is great and really speeds up my work, except when it doesn't work. Then it's great to be comfortable falling back to something rock solid and unbreakably simple. I never have to "fall-back" multiple times in successive frustration. There is one fallback and it ALWAYS works.

To me it's not worth learning the "in-between" tools for the extremely limited circumstances that I'll need something less than IntelliJ but more than vim/bash. I even hesitate to customize my vim much because I need to rely on it as a fallback on nearly any system, and on novel systems I can't rely on my customization.

I'm not dogmatic about only sticking to these - I'm comfortable with VS Code when it's what my employer/workgroup provides, and I'm comfortable with Sublime, as it's particularly portable (can be run off USB). So sometimes Sublime is the fanciest option.

But anything in between JetBrains and vim needs a real "reason" to bother investing the time to learn.
