Trinidad's 2-fisted attack would have given him the edge. I saw many of Terry Norris's fights:

2 with Simon Brown
Sugar Ray Leonard
Julian Jackson
Meldrick Taylor
Maurice Blocker

Norris was an awesome athlete but he was also a hothead who could not always control his emotions in the ring. Occasionally he had defensive lapses too such as in the 1st Simon Brown fight and his earlier fight with Julian Jackson. Trinidad didn't have a great chin, but he almost always got up from being decked. Trinidad had more raw punching power too. I would go with Trinidad by knockout.
