It really all depend what you want to do. If you want to be doing research at a big institution then you should go to the top. However, all that falls out of the windoe if you publish before you go out to the market. If you do that, then you will be ahead of the game no matter what school. The issue is that it is difficult to publish unless you've already got some experience, like writing a dissertation. Utah gives good teaching opportunity and their placement seems to be at liberal arts colleges, and mid level research universities. So it all boils down to what kind of job you want after PhD.
