I love the duty uniforms and think they were magnificiently done. However, they grate on me because they don't fit thematically with anything else in the movie. These Starfleet professionals dress in uniforms that are so neat, clean, militaristic... until they go on duty, dressed in a rainbow hodgepodge of frumpy clothes.
I loved the uniforms in this movie. That being said, I also liked that Starfleet had shore and working uniforms like the USN. The navy has two sets of khaki unis for officers--one is more pressed and neat while the other is more frumpy and loose. The former is worn mostly ashore, while the latter is worn aboard ship.
In a working environment like a ship, you'd want something a little looser and easier to move around in. Of course, I didn't think the TOS-inspired nuTrek uniforms were frumpy or loose. They looked every bit as form-fitting as all the other uniforms in Trek.
As to what nuTrek got better:
The cinematography had a kinetic energy that was sorely missing in Star Trek, not just TOS but everything that followed.
