The 195 was a more posh version of the Sporstar OB. It was produced in 2000 and 2001. It is the same hull as the venerable 1995--1997 Pro Star 190. It will have a little more bow weight due to the seating, but the wake will be comparable. Depending on the engine transmission combination, it might have a bit more get up than a 197 due to less wetted surface.
In the end, either boat should ski well and condition and features should probably be more indicative of which boat to buy.
