I was looking at both when I was buying new tires this past spring. I went with the Nittos for the looks of the sidewalls. The Nittos just look more aggesive than the Toyos, since the Toyos are just a plain smooth sidewall. I like my Nittos, they are a great tire.

 

The Nitto's are extremely quit on the highway. Much quieter than my BFG AT KO's.
