I pretty much agree with Bill's assessment except that I have no personal knowledge of the differences between the T2 and the T3. Given what you have stated in your original post, I also think that you would be happier with the Yamaha. Like Bill, I too would choose the Korg if I had to choose just one, but that is based purely on subjectivity and should not be considered when choosing a keyboard for yourself. Your needs, tastes, applications, and work style, may be completlely different from the other persons.
