I adore the Excelsior class, and always have. It's a majestic class, with a greater than even the Galaxy class (a relative opinion I know, but no less valid :-) )
Then again, the Akira class, from the moment I laid eyes on the USS Thunderchild, is a ship I can't forget ever. There is much unknown about this class, it was thrown in like all the others (Steamrunner, Saber etc) in First Contact and only given more air time because of DS9. And I thank the producers for every second of it LOL!
