When I watched all the Star Trek series for the first time (except Voyager, which I watched even earlier), and the movies, about 10-15 years ago, I prefered the First Contact /late DS9 uniforms. I also liked Voyager and early DS9 uniforms a lot. I guess that those I didn't like those bright and colorful uniforms from TOS and TNG, and I prefered the darker ones, with less colors and more grey black. I guess I also like to wear black myself, that time.
Well, now, maybe because I love seeing other people wear colors, and I love colors myself, I love the bright colored uniforms, and those First Contact uniforms are too black and grey for me. My favorites are TNG uniforms, seasons 3-7. They look a bit more like uniforms than TOS ones.
Somehow I love the spirit and bright future of TOS and TNG universe the most, and those uniforms really fit them.
Also, my favorable mention goes to TNG uniforms from seasons 1-2. Although I don't like them that much as
uniforms, I must admit I really like how tight they are and I love seeing TNG actors (while they were still younger and slender

) in them.
