Well, none of them involved the girls furiously playing quiz games against each other, throwing dodgeballs at each other, playing speed pictionary, getting hit with pies or eating bugs like AKBingo had for most of its run.

HKTBingo is single focused, but focused on comedy which is inherently most interesting than dramatic acting as their express goal is to make the audience laugh. But it really is best after they start performing their prepared routines.

And SetoBingo had a different subject each episode.

But if you have already watched AKBingo all the way through, do you even need to know more than that HKTBingo has Murashige Anna and Tanaka Miku and SetoBingo has Okada Nana to know that they would naturally be better than SKEBingo?
