I guess I judge it a lot on how mememorable it is. FFXII did have some good boss music but I barely remember it. For XIII, I do remember the intro but it kid of fizzles out from there. Admittedly I didn't play XIV and just started XV.

For Uematsu, even his worst tracks are still memorable. My complaint about video game music theses days is that you barely remember it even if it suits the scene. It's just part of the background.
