On a purely visual level I think ENtetprise has felt more "Realistic" then any other trek , primarily due to set design and costumes. But it's not nor never been a show tied to realism. As for ID, I didn't see anything that would make me think that universe's would be seen as more realistic. But in fairness I can't say the same about Trek 2009. With most of Trek we have had a crew size (TOS, TNG, VOY less sure about DS9 and the Defiant). So with the the exception of the Galaxy class ship, I never saw the ships holding anywhere near the shuttle facilities they would need. The Galaxy class had enormous interior space that coud easily hold dozens and dozens of various shuttles, and get them to the three shuttle bays. At least with Trek 2009 (and without being told crew compliment) we see a fairly large supply of shuttles. So that in emergencies where the transporter is useless, a good number of crew could escape and escape in a manner more then just drifting in life boats which would seem to be extremely easy targets for threats to eliminate. That is the one thing I think a larger ship does allow, that a long ranch ship should have, especially if those ships aren't seen as serious death traps.
