It's kind of like which color is better, blue or green. These guys are all great! Seriously, i cannot imagine arguing about who is "Better" in somethign like this. At some level you get beyond being better and you are just different than the other guys. Music contests are often just a matter of who has it all going on at that one moment and who is sitting in the audience at that particular moment. Once you get past those who really cannot sing ever anyone can be the Best at one particular song for one particular moment in time.
Music isn't really a sport anyway, anyone who participates is a winner the way I see it...

Oh, the 4th soloist was by far the best though...
