Is Demi truly the best X Factor judge?

True but Cheryl is the reason X Factor became iconic in the UK.

How can you do a poll about the best Xfactor judge of all time and NOT include The actual Best Judge of All time???

There were different rounds, In the first one there were all the judges, then the next round there were the top judges from the last round etc. until there were only 4 left

Numbers are saying it's Nicole Scherzinger who didn't lose any of her acts until the 8th week.

This is THE FINAL. There were 3 other rounds Who is The Best Judge according to you?!

Simon

Firstly it's about Judging not Mentoring which are two different things.
Secondly, Ratings>>How many acts you have left

Demi and Nicole.

Ok, so is your sense, Nicole is a better judge than Demi, Britney, Simon and L.A because last year's X Factor US had MUCH higher ratings

Cheryl Cole > Dannii Minogue > Demi Lovato > the rest
