Perhaps Nick, but ease of use is important to me as well. I want to perform, and think a little less about the other things, if that makes sense. I like more keys.. what can I say ? Also sound is subjective anyway, and I like the sounds coming from both of these arrangers. I have a much deeper sound palette inside of my laptop ( many gigabytes of high quality sounds and modules ) than either of these arrangers is going to give me anyway, but the main point of going for an new arranger is that I'm also looking for something that I have to think about less to play.
In reality, my software OMB setup sounds better than my PA80 does. Not the styles per se, ( though often I like the simpler Yamaha styles ) but the lead voices are so much better coming from the laptop that it isn't even close. The caveat is it's not always so easy to setup and navigate more advanced features in the laptop when I compare it to a hardware arranger.
