The former Pussycat Dolls member was the runaway winner in our Best Judge poll, scoring a massive 55% of the overall vote.
Over 15,000 fans took part in the survey.
Gary Barlow was Scherzinger's closest rival, picking up 27%, while Tulisa Contostavlos only managed 10%.
Louis Walsh, who has appeared on every series of the ITv1 talent show, finished last with 8%.
Scherzinger's Boys category was the most successful in the recent series, and she managed to keep all her acts in the competition until the quarter-final. The final two - winner James Arthur and runner-up Jahmene Douglas - were both mentored by the US star.
The 34-year-old singer was originally dropped from The X Factor USA after only one series.
