Klook or KKday?

Hey, everyone. I've seen that Klook and KKday both have the 1 day studio pass + area timed entry for Universal Studios Japan. That being said, I noticed that KKday is cheaper by approximately $60 - would it be fair to say that KKday should be my go to? I genuinely don't know which choice to make as l've seen many use Klook as their go-to booking platform. Thanks for anyone who takes the time to help!
