My personal experience with these two keyboards is that both have excellent sounds. The Tyros has more "sweet" sounds and 300 styles while the MoES has very good sounds and 1700 arpeggios, which can be strung together to make something similar to styles.

I took the MoES6 I had back and traded for a Tyros because the Operating System on the MoES is not very user friendly whereas the one on the Tyros is very much so. You can certainly learn the MoES but it will be a lot more work because it is NOT intuitive; you will have to "learn" (ie, memorize) how to do things because it does not flow in an understandable manner. If you get a MoES you will need to spend a lot of time at Motifator.com if you want to know any more than how to use it superficially.
