As tyres for 17in wheels are lower profile than those for 16in wheels then I would expect them to give a harsher ride, but I don't know if it would be noticable compared to the 16in tyres.
I would also expect tyres for 17in wheels to be more expensive to replace than 15in or 16in tyres, but I am only guessing about that.
