IME, ypao is good at setting levels and distances. It’s useless for subs. Audyssey is the best of the three for subs, but I have been using LR bypass and limiting EQ to 300hz for the other channels. I think Dirac is best overall.
As far as easier placement in the corners. I get that. It’s a lot easier. Again, it will work best for Auro that way, but for Atmos I feel you’ll be left disappointed but then say Atmos sucks, and it’s actually the layout not supporting it. Don’t get me wrong, there are a lot of Atmos tracks that aren’t that great, but that’s been true for a long time of all formats. Some are good, some are not. But when you here objects in 3d space , IN your room and not “around” it, it’s pretty amazing. I’m not a big social media guy, and most of the people I see on YouTube are dumb, save for a few. Damn I sound like a curmudgeon…lmao!!!
At the end of the day you have to do what’s best for your situation, and that can be different for all of us. I chose my path and won’t be looking back. I hope whichever way you go will be best.
