Re: Federation Versus The Romulan Empire
TNG - Galaxy Class> D'deridex Warbird
DS9 - Yet again the Galaxy Class seems to outperform than the D'deridex Warbird.
TOS - Constitution Class> Romulan Bird of Prey/ Romulan D7/ Ktinga
Nemesis - Sovereign Class> Valdore Type Warbird
I wonder where you're getting your information? Rarely have we seen any of these ships go toe-to-toe one on one. The only one I can really remember is the Constitution vs. a Romulan Bird-of-Prey. Even there, I'd say it was more about who was in the center seat than them having the superior ship.
