Javier Colon, The Voice Winner, Down to Battle X Factor, American Idol Champions

The Voice reigning champion Javier Colon has accepted Simon Cowell's idea for the ultimate musical showdown - a battle between TV singing competition winners!

Simon suggested pitting the champs of X Factor, The Voice and American Idol together in a singing smackdown, with the goal of determining who reigns supreme.

Javier took to Twitter to accept Simon's "super final" challenge:

"So @simoncowell recently proposed a face off btw Idol/Xfactor/Voice winners. I really respect the other shows and winners a lot but if U want a battle I'm IN!"

American Idol producer Nigel Lythgoe also responded on Twitter last week, but he was less willing, making a thinly-veiled claim to Idol's superiority:

"@simoncowell suggests the IDOL winner should take on the voice and x-factor winners. The problem is the Idol winner will be a star by then."

Ouch! Idol is really digging in against its critics these days.

With X Factor allowing managed talent to participate this season, and The Voice getting bigger ratings than ever this winter, the ante has been upped.

Will past and future champions step up to the plate?! This show would likely never happen for myriad reasons, but we ask you: Which show is the best?
