They don't appear to be my type but for discussion sake I would think that the one in blue would be the one I prefer. Both women appear to be equally at ease with the camera and willing to have their perceived "charms" discussed at length by a bunch of cartoon fighter plane drivers...so they can't be all that bad.
As for the one in purple there is something that I just don't quite like. I can't put my finger on it but it is there.
BTW where the hell was that photo taken? The writing on the lit up advertisement/cooler visible in the window doesn't appear to be anything I have seen in Texas.
