Default ECU differences on C5

I read a post on a corvette page on Facebook where someone stated that if you want to tune your car you should stay away from 97 and 98 model years. Is there a big ECU / software differences between the years on C5's? If so, can someone explain the differences?

Also interested in info. Got a 99 on the way but I always heard the 2000+ ecu is more desirable.

Wondering what the best route is for tuning a car with basic bolt ons at most.
