Bebop, the quoted words was missing in your post, and that is the main
reason for my reply/post.

As I always use to say when the "what is the best" or "what shall I buy"
discussion at the forums are going on, every brand of those topline
keyboards is great, and they have functions unique for that brand.
I think it's the needs and personal taste that the person who buy and
play it who counts.
For me it is the composer and easyness to edit and mix styles etc, and
so far I've not found anything else who suits my needs like that in any
other brands.

I can't imagine that Yamaha is twice as good as i.e. Technics or other
"top line" keyboards, that is to use too big words, just as if I should
say that Technics is twice as good as others.
Better stay reasonable cool, and compare correctly by the technical data
and the material quality.
If it is twice as good for one users personal needs, it's not nessesary
the keyboard itself who is soooo much better.

Regardless of what brand,
Happy playing!
