From the uniforms, to the sets, to the filming model, *nothing* aboard 1701-E carries over any of the warmth of 1701-D, which is something that I reckon was as much a part of the TV show as any of the main characters.
The D was too warm and fuzzy. It seemed more like a pleasure cruise ship than a warship. The D should have been used as a luxury passenger liner for space tourism.
The E had a very militaristic vibe to it. It looked intimidating while the D did not. However, I think neither the D nor E compared well to the TMP refitted Enterprise. The Enterprise in TMP had the best look of all. It looked like an efficient warship without appearing intimidating, which would make it equally useful for diplomatic missions.
