My causin owes a PSR-9000, its souns/styles are basicaly like older PSRs, only PSR_9000 has more mixer controls tone editting and all other not very usefull stuff.Some people say that 9000 is same as PSR-9000 athers say it is somehow different.But TYROS is the newest Yamaha arranger so Tyros probably should be better than 9000 and of course(as I think)much better than PSR-9000.
