Just as a general comment I'd like to throw out there to everyone.

It's not contest of mine is better than yours, and there is no such thing as a universally better keyboard regardless of how advanced it is.

We are all musicians here so I don't have to explain that music is from the heart to you guys, so just remember.... Technical specs are fine and all that but, the instrument you choose is supposed to be the best one that allows you to express what's inside you. That's the most important factor. Technical specifically are no means to measure how good that keyboard will be at allowing you to express yourself.

We have all different needs guys so the best advice I can give anyone is go with your heart after you do your homework on what's available. Test the hell out of them all too.

The only thing that matters is what makes you happy most and what allows you to express your music as best as YOU can.

Regards
James.
