I think that they both look great. One thing you might want to consider is that from certain angles, beveling, or 'fake bump mapping' makes panels and other things look like there sticking out when they should be sticking in, and vice versa. From certain angles it can make things look pretty funny, especially windows and escape pods. This is the reason I've decided to go with flat details on my Galaxy.
Just something to think about.
The other nice thing about leaving your textures un-beveled is that when a game comes along that you can use realy bump mapping or normals in, then the ship will be usable without looking comical.
My 2 cents.
Fantastic looking ship Glenn, you're really doing it justice.
