A lot of the advice in the Audyssey threads and articles/guides also applies to multi point YPAO.
A few differences I'm aware of:
1. YPAO is pretty much useless for sub EQ, not just under ~30Hz, but in general. However, the 20x0 and 30x0 have separate levels and distances for dual subs, which is like Sub EQ HT on the Audyssey based AVRs minus the (actual) sub EQ part.
2. Audyssey only uses the first mic position for setting levels, distances, and crossovers. YPAO uses an average of all mic positions, though the first spot is likely given more 'weight' than the rest.
3. The speaker EQ includes both the hidden impulse response filters (RSC, which is Reflected Sound Control) and the visible PEQ filters you can tweak if copied to the manual PEQ preset.
The sub EQ is PEQ only and is likely only useful if you tweak it manually in REW with the UMIK-1 calibrated USB mic.
Audyssey uses the impulse response filters throughout everything and there are no tweak able PEQ filters. However, the Audyssey editor app on mobile devices is probably a much easier way to tweak EQ and other useful settings as it is more intuitive and doesn't require REW or UMIK-1. Also, you can limit EQ to the modal range, which is somewhere between 200Hz and 500Hz, depending on room size (likely 300Hz or lower in most HT rooms).
4. The 3D angle/height is a useful feature with YPAO that optimizes the object tracking used in Dolby Atmos and DTS:X soundtracks. It also optimizes the Cinema DSP modes, if you are into that.
