Boats I would consider:
1991-1992 MasterCraft Prostar 190 (great wake, carbureted engine)
1993-1994 MasterCraft Prostar 190 (fuel injection, softer wake, but some spray at shorter lines)
1995 MasterCraft Prostar 205 (essentially the same wake as the 1994 190)
1995-1997 MasterCraft Prostar 190 (firmer wake, but less spray)
1997-2005 Nautique 196 (great wake, great tracking)
1999-2009 Malibu Response LX (low, firm wake and still easy to cross for beginner)
2014+ Centurion Carbon Pro (great wake)
I've skied an old American Skier that was quite good, but you are probably getting into wood construction and I would avoid that unless you know the previous owner and how the boat was maintained.
No experience with other non-big 3 boats. I had inconsistent experiences with the Malibu LXi. Some were good, some were not. You want to ski and drive any boat you are considering, though.
Full disclosure: I have owned a 2000 MasterCraft 205 and still own a 2009 Malibu Response LX. The 205 was very good, but couldn't get ZO. It did also have more of a 22 off bump than anything else listed above.
For those wondering why I didn't go beyond 2005 with the Nautique, I skied some later models that had some wake issues and wasn't sure if those were one-off quality issues or some change affecting the wake design.
I didn't list any newer boats (other than the Carbon Pro), because the pricing changes substantially.
Edited: I accidentally omitted the 1999-2004 Malibu Sunsetter LXi (you must get the model with the cantilevered stern), which has a wake very similar to the Malibu Response LX hull upon which it rides.
