I personally own a psr 9000 and a roland e80 they are both beautiful boards. My house was broken into and the snagged my tryos and all my collectors guitars. So i can honestly tell you for what they are like comparing a talor to a martin a strat to a les paul.All are premium arrangers. But yamahas programing is very sterile and roland's sound a very woody and accoustic. Each company has a very viable musical slant and perspective.
The e80 is lacking in a break fill button multi pads and a step entry chord sequncer which i and others have told jan vogel at roland that this former g1000 and em2000 and g800 option needs to be written into version 3 upgrade. The e80 sounds like nothing else sound and stlye wise also you it displays instantly for you good chords on the spot in the base of the lyrics window and on an external tv for jammin.
All these companies practice string em along marketing thats why i'm still pissed at them all. Our arrangers should be over the top better each new model and not lacking in previous genius features.
