Legend
Even before Seven of Nine, Voyager did not seem very interesting in character development, though, when I see parts of the reruns, it had - but unfortunately, they ignored some characters (Once again my favourite example: Ensign Kim, the poor boy, has served 100% correctly and perfect for seven years, was never promoted...)...
All in one, they could have done much better with the characters.
When I am looking the reruns of DS9, I come even to enjoy the first, sometimes weaker episodes of the series, and I can really say great character interaction and development.
For the uniforms, most have been said (well, actually, this applies also about the qualities of the Startrek series - there are dozens of threads here about it
)
But for (made up) "ingame" (as we would call it in roleplaying games
) reasons for the Voyager/TNG/DS9:
Probably at some time the Starfleet decided that the different colouring of the "branches" didn`t make sense, because the officers all had the same training, and everybody did their duty (usually, in formidable ways), so everybody should wear the same uniform. And they decided (because most of the "deciders" work aboard space stations and liked their uniform) to use the "space station branch" uniform
The later chaning of uniforms might be explained by this, too.
A note about the TOS: Every ship was meant to have its own emblem, but that later changed (at time of the movies).
Maybe they reorganized Starfleet, and decided they wanted a sign for the whole fleet, and since the Enterprise was the most famous ship, they used that.
