How much footing are you doing? A mid-90's Malibu Response/Echelon, Sportster, Sunsetter will have the best footing wake by a mile. Malibu was just starting to hit a stride in the mid-90s with some really good boats for the time.
90-96 Ski Nautique set the standard at the time for driving experience, tracking, spray, build quality, and ergonomics for what we'd consider a modern ski boat today, no question, by a mile. BUT the long-line barefoot wake is not great. Slalom wake is pretty good. Not a footing boat though.
91-94 MC people absolutely go bonkers for here but the driving experience and ergonomics/layout are awful IMO so I highly disagree with rating that boat so highly. Not a modern driving experience. Highly rated slalom wake for the era, never footed one but the footing wake is probably better than the SN of the same period, I'd guess.
95-97 MC could be an interesting option though I have no experience with those.
Reliability will be similar across the board, I'd avoid TBI fuel injection setups if possible from that era, maybe they are more serviceable now though. 95+ PCM GT40 in the SN is the of the best EFI powerplants ever made for a ski boat and the LT1 Indmar engines are also terrific EFI motors. Otherwise, go carb.
