I've always had a special fondness for the Nova-class - like Voyager it's got the sleekness of the Galaxy-class in a smaller, more techy-looking package that I think makes it a bit more relatable (I love the D, but I feel there's a degree of style over substance to it), but without the Intrepid's shortcomings (IMO), the too-long saucer and stubby little nacelles; instead she's got some inspiration from the Sovereign-class, but without being a show-off about it.
