Yamaha boats

My brother in law is looking at getting a Yamaha boat (either AR210 or AR230HO). He's looking mainly for a family runabout boat. He does wakeboard, but not seriously. His big thing is safety with the kids. With a Yamaha jet boat there's no worries about the prop chopping anyone up.
I don't know too much about jet boats. What are the pros/cons of a jet boat versus a direct drive or vdrive?
His arguments for a jet boat are:
1. No prop=safer for family/kids.
2. Planes MUCH faster than prop boat.
3. Accelerates MUCH faster than prop boat.
I'm thinking to myself, "if points 2 and 3 are true, why doesn't any pro tournaments use jet boats for towing?"
Those out there with jet boats, are points 2 and 3 true? Also, how is the wake on these boats?
Thanks guys.
