What is great, what bugs you? (especially if compared to tyros or psr910 if you can)

I did try it in the store so I have general idea. I have to say I like the tyros, but it is just totally crazy expensive here. They PA3X is at least 30% cheaper here so I am thinking maybe that one.
Give me your honest opinion vs. Tyros.
