IRV still has the problem that gaining a few percentage points can cause a candidate to lose. I'd prefer approval voting's potential paradoxes over that possibility any day.
I'd also consider a non-majority approval victory a highly desirable outcome, and the way politics goes right now, it'd be more like a 40% candidate with 85% approval beating a 51% candidate with 51% approval.
