For me I would have to flip a coin to choose between the Galaxy class and the Intrepid class. As much as the Galaxy class' bridge is bright, simple and gives a cheerful feeling (something which should be present in a ship devoted to exploration), the Intrepid's bridge gives a feeling of what the bridge actually is. It gives the feeling that it is used. it can seem rather dim and foreboding, especially when the ship is on red alert. It seems more realistic, even though the Intrepid class ships were essentially science vessels and not war ships.
