When I did jailbreak, it was never about apps and rarely about high-level features (I did use NC settings before that was an official thing, and I installed a torrent client and some emulators, I think).
I jailbroke because I wanted to have access to a local terminal and write and execute arbitrary code on the phone - nothing major, mostly small bash and Python scripts and some C code when I was learning how to program.
It was also a philosophical thing: I want to have full ownership over my phone, whether I need that on a day-to-day basis or not.
I moved to Android when iOS jailbreaks started to become rarer and slower to appear, and more and more jailbreaks started to be tethered-only. There are only so many hoops I am willing to jump through when I can instead buy an Android phone that officially supports unlocking the bootloader and rooting it.
