Season 11 is my favorite of the old Idol be because of the diverse artists, memorable contestants, good song choices, and great singers that kept me craving more week after week.
Of the new Idol, none of the seasons have been amazing in my opinion. I agree that Season 18 had the most potential and couldve been one of the best Idol seasons had Miss Rona not arrived. The Top 20 was super diverse with great vocalists and artists, but the competitions format didnt allow for stellar performances or growth from contestants.
