My maximum crunch is around D&D 4e. Though even there I'd prefer to see a streamlined version where some of the fiddlier less-consequential bits (like Feats) are removed. That's my upper bound these days, and even there I'm not sure I'm up to learning a brand new game at that level of crunch rather than playing a game at that level that I already know. (I might be more inclined to try Strike! with the tactical combat options than actually running 4e again for example)
But on average I prefer less than that - 5e and 13th age are both about at the right level for me as a GM (though I prefer 13A combat on the GM side over 5e any day). Players in my new group are mostly 5e players and are happy with the level of it.
I will say that my maximum crunch levels have declined as I've aged. At the rate I'm going I'll be down to only wanting to play Lasers & Feelings by the time I'm in the nursing home
