To me there are certain voices that are a lot better on the Genos than on the Tyros 5. The Revo drums are very realistic, and not mechanical like on the Tyros line. The DSP's are more realistic in my opinion. The Kino Strings, I am still undecided about , I can take them or leave them. It could be my style of play, perhaps if I played more symphony type music I would like them more.
To me the best improvement is the new interface. It is so much easier to use and very quick to get to where you need to be. The file system is easier to use as well. The playlist function, take a bit to get used to after using Music Finder for so long, but once you get used to it, it is another improvement. The ability to work with Songbook+ is also a lot easier to use and link your sheet music to registrations, and vice versa, then it was on the Tyros.
Just my two cents!
