It's true. You don't see idol groups right now doing what 2PM did. At the height of their fame, they were average 20-22 years old, and yet they were manly beastly men.
Till this day, none can beat 2PM as Beastly/Manliest Idol ever, even if they act cutesy and soft, they still exudes manliness, masculinity and toughness... That really showcase that their image/persona as an Idol and as a person not that much of a difference and that makes them much real and not fake...
2nd gen is seriously the best. Netizens only expect live singing and even had a huge issue when Tara debuted while lip synching. Newer idols now despite having good vocals mostly lip synch or have a loud back track or prerecorded vocals. Y
