Definitely not my favorite pianist and I don’t love everything he did (nor am I interested in exploring his catalogue in depth), but he was on a lot of classic records and provided a lot of value added to my ears. Would rather listen to 5 min of OP than 5 min of Bill Evans.
I think the comparison of OP to AT is off, maybe Freddie Hubbard is a better analogue?
I think Ethan Iverson’s post on him is pretty useful in terms of explaining why OP has raised such hackles over the years:
