For pure raw talent of voice alone, Josh wins hands down w/o a question for me. *However* each have a different style and each are wonderful talents in their own right. For a more pop style, Clay's voice is perfect! For the style Josh does, his is perfect! I will say that I love them both equally... they get pretty much equal play time in the CD player and I have tickets to see *BOTH* in concert in the next month or two. So I am far from bashing Clay, but Josh's voice wins for pure sound alone.
