It is refreshing to see that we have had some good and diverse opinions on this topic.

Just to be sure, I don’t mean to say that one keyboard may not have features and ways of doing things that may be better and easier than other keyboards.
For example, the Tyros 2 may have SA voices and rootless chord voicing recognition. The Genesys may have a 32 track sequencer and styles with 4 intros, 4 endings 4 fills and 4 variations, the G-70 may have 76 keys, the Wersi may be able to use VSTs and so on.
However, the value of those features on each manufacturer’s keyboard is only valuable to those who need those features. Rootless chord recognition and the ability to play high quality VSTs sounds may be of value and necessary to some but may not mean anything to others and the same thing can be said for a harmonizer, 32 track sequencer, a style creator, 76 keys, CD burner and lots of other features.

Arrangers have come a long way over the pass 10 years. Each manufacturer is trying to out do each other with new and innovative features. Those innovative features may not be wanted by all.

This is why I don’t think there is a universal “best” keyboard from any one manufacturer. It is the individual keyboard player that makes a keyboard the best for his or her self.
