Which star trek uniform is the ugliest?

The uniforms seen on the "future" versions of the main characters in Star Trek: The Next Generation's final episode "All Good Things" were the ugliest things I've ever seen. Still some fans I've met think they're the best uniforms out of everything else seen in the entire series (TOS, TNG, DS9, VOY and ENT). I think they are hideous, but hardcore trek fans are somewhat fashion blind it seems.
