Because I like having a stable system with a known "good for" date, rather than "when it's ready". I particularly like using LTS for systems that I don't want to have to touch very often...just set unattended security updates on and leave it be. I realize I could do something similar with Debian, but testing isn't generally stable enough for the use cases I have in mind, whereas stable gets stuck with some very old packages. If I need a new package toward the end of the lifespan of a LTS, I can often find PPA. If not, I'll just compile it myself. It's just my preference. To be honest, probably a big part is that Ubuntu is mostly what I've used the past decade.
