I intend to follow A.C.E because they have distinct vocals and they seem to be great dancers, too. To be honest, I can't really get used to Cactus's beat though. It's kind of chaotic and there's to much going on for my liking. I'm still pretty sure they'll drag me into their fandom sometime..
I fell hard for MVP though. When I first listened to Take It I was just busy crying over LC9 but MVP's version was stuck in my head for days, so I had no choice but to listen to their whole album and it's such a great debut. And boom! Now I even have a bias, lol.
I think I listened to the debut tracks of Blanc7, Varsity and Topsecret, but I didn't hear of 14U and SOC yet. It's about time to change that. ;)
