X Factor vs American Idol

There's a lot of discussion out there regarding which is better, X Factor or American Idol. To me, it's all about the contestants. For instance, in American Idol Season 9 vs Season 10, Season 9 had too many guitar-strumming singer-songwriter types, while Season 10 had a fine variety of fine talent. So Season 10 was much better. X Factor Season 1 did not have compelling talent.
