Have to agree about how Uhura was written, given the time in which she was created. I would also feel more comfortable following her orders than Chekov's, can't really say why though.Uhura was limited by the writing in that she had very few opportunities to shine but I always felt she had more of a command presence than Chekov. Admittedly he was quite green in TOS but even in STII, I thought his command skills were pretty weak. Uhura in STIII on the other hand? Yes Ma'am!
