I've always been a bigger American Idol fan, but I don't like the stipulations put on age and the fact that they can only sing. Also, Paula Abdul is beginning to ruin the show for me, while I LOVE to watch Sharon Osbourne. So I would call it a tie unless Idol shapes up next season.
for me, i think both are just good. American Idol focuses on singing but America's got talent gives a lot of opportunity for different talents. but then America's got talent is more fun to watch because it is not too serious.
