The Katy is over 230 miles and the RIT is a little under 50. They are pretty similar as far as the trail itself goes. The Katy has been around longer and goes through more populated areas from time to time, so there is more to see and do. The RIT is less developed and only goes through a few small towns / villages. Food, water, lodging, etc are more available on the Katy, in general. Just depends on where you want to ride. The experience isn't much different when you're on the bike on either, but your options for off bike activities are higher on the Katy.
You can do both. The RIT intersects the Katy at Windsor.
