They are less fuel efficient then propellors. They are better when it comes to hitting things such as logs, however you can still damage them pretty heavily if you run aground and suck a lot of sand/smaller rocks etc through the impellors. It is also possible to such debris into the impellor like ropes and so forth.
I have only run smaller boats with jets and am not super familiar with larger yachts with them. I'd prefer propellors myself.
