I guess it comes down to W&L: cheaper and a one of a kind small environment vs. UT: pretty much has every other advantage. Though the hard part is figuring out what is more important.
i think you should decide based on what part of the country you want to work in, and if you don't care, choose based on where you feel more comfortable. you seem to like the size of W&L (remember, UT breaks the class up into smaller sections).
i couldn't decide between UT and UCLA for a long time; i finally imagined myself walking around both campuses, and found out that i would always wonder what it would be like at UCLA if I went to UT.
