As one who owns both a Tyros 3 and a Motif XF I can tell you that workstations do add value. Now I don't gig but rather compose and record my own music so my needs are different. What I found was that the Tyros and other Arrangers have a much different sound than workstations and are not oriented as much as I would like to more modern backing and arrangements. While there are hundreds, even thousands of Styles available there were only a small number that suited my needs. And in my experience creating Performances on the Motif with it's intelligent arpeggios was far easier than creating a style. Where the Tyros excelled was in the sound of specific acoustic instruments and I can easily use those with the Motif although I found that workstations IMHO have much better Piano voices.

Even if you gig or just play a Motif or a Kronos it can open up a whole new world of sound. Is there a lot to learn about how to use them? Yes. But once you have it's great fun and the combinations of sounds and accompaniments are endless.
