I run a Denon 2805 and have been happy with it.
As far as the YPAO goes, I think all the ones you mention have something very similar.
For the most part I use the auto setup on mine just for calculating speaker distance and levels. In my opinion the EQ part of ANY of the auto setups arent very good.
You might also look into the H/K 635.
It has a new auto setup that is (as far as the EQ part goes) supposed to be better.
Good Luck
