I've got a RX-V1400. It's a good receiver and I like the black chassis color. YPAO is handy for certain things like speaker polarity and level checks. However the EQ and crossover detection isn't perfect (at least in mine). It sometimes picks a 200Hz crossover, and once set contradictory + and - EQ change at the same frequency on the same speaker. Overall it's a nice feature but it's not perfect.
A big advantage of the H/K AVR430 (don't know about the 330) is superior bass management. It can do bass management for 6-ch analog inputs (generally required for SACD or DVD-A). It can also use different bass crossover frequencies for each speaker.
