Just to add my two cents into the conservation.
I just don't like the nuEnterprise "super-size". The overall classic Enterprise visual cues suggest a much smaller size (close to the original). Whereas the Next-Gen Enterprise, gave you a sense of real huge scale, based on the visual cues.
For me personally, and from an engineering standpoint, the TMP Enterprise
had the best representation of the ship, size and scale. Plus that move showed that it all depends on how the ship is filmed. It showed that you still fit fairly large sets into the ship, and still get a real sense of huge scale.
