I personally think 2PM is probably the strongest and most mature group in kpop. They don't care about competing with other groups when they schedule their comebacks, they've been that way since debut, they just go in head strong and tackle the big names unlike some groups and that's amazing. It's the music, fans, growing to become better and team work that matter most to them. You don't hear many groups say that out loud cause it seems that fame and being #1 is the only thing that matters most.
