I voted ST09 love how they used the delta symbols as a pattern.
My 2nd favourite has to be the TMP yes they look bland and yes they look like pyjamas but TMP was a big film at that time and i don,t think the TOS uniforms would have looked right on the big screen and with all the different changes to set design they would have looked out of place. However they should have incorporated the gold,blue and red departments into the pyjama look it worked for TNG.
