As the owner of both (I have an '88 and an '07) they're aimed at two different audiences. My '88 feels like an indy or a grand prix car on the street. My '07 is a more practical bike for moving at speed with a moderate amount of cargo. It's also more comfortable as the '88 is set up to be more aero in positioning for all out road racing and the '07 more upright. If they had both back in '88 I would take a hard look a the characteristics of the newer bike and buy it. Why? It fits better and is more versatile. It can do the racing role sufficiently well and still function as day to day transportation.

Don't misunderstand I still feel my '88 is a thing of beauty, but it's a thoroughbred where I really need a quarter horse most of the time. Not an all out racer..
