Which group is the best among idol groups?

Posts were recently released on an online community with the caption, “The newest version of girl groups ranking,” and “Boy groups ranking.”
SNSD ranked first and proved that they are the best girl group. The group was followed by 2NE1, T-ara, Wonder Girls, and KARA.
After the girl groups ranking was released, ranking for boy groups was also released.

On February 21, an online community posted pictures, which are captured images from tvN’s E News, which aired in January, 2010.
The show aired boy groups ranking, which was made by 30 entertainment reporters. The ranking was based on evaluation criteria, including, popularity, income, singing ability, dance skill, and fashion sense. As a result, TVXQ ranked first.
A person who posted the pictures said, “Since the ranking was made last year, Infinite and CNBLUE need to be added.” The the person posted ‘The newest boy groups ranking’ and TVXQ still ranked first. The group was followed by Super Junior, Big Bang, and 2PM.
People responded: “The ranking is just for fun.” “The result will be changed if we rank groups again.” “TVXQ members are the best!”

Anyway, this ranks is not the newest but well, I must say, DB5K is the best!
