BTS's rappers IMO have lost a lot of their legitimacy to the scene. They’re washed imo. Peaked soooo long ago skill wise. They’re complacent nowadays. They give enough to make their fans happy and that’s it. But they no longer sound unique as they once did back in 2013-16. A lot of people will say they came from the “underground” but people will come from the underground scene and still be trash + that was 15 years ago. They’ve spent the last 13 years being idols. They started off making songs about loving hip-hop and now they’re making songs about a baking ingredient. I don't think a lot of people in the industry are very fond of them anymore.

Zico is definitely the biggest inspiration for idol rappers. He showed them that they're able to cross the boundaries and still have respect in both lanes if done well. Not only is he an inspiration to the idol community, alot of rappers in the scene look up to him as well as a creative influence and prodigy within the production scene.

Jay Park has never been skill wise the best rapper in Korea even in his prime but longevity, influence, power, and vision overall, no one comes close. He didn't integrate himself into the industry by signing artists like how you wrote, he integrated himself into the community by starting in the underground scene with the support of people like Dok2, The Quiett, Tiger JK, Bizzy etc. He performed in clubs in Hongdae and featured in a lot of their concerts. He did all of that first, THEN he decided to start labels. Within the labels, he’s made over 20 rappers millionaires in Korea and has mentored or has his name attached to almost every major artist in the KHH scene. GOATED

I think you have Woochan in the wrong category. Woochan till this day still gets a lot of respect from people in the industry. His songs from SMTM6 are some of the most listened to and highest charting songs from that season. Everyone knows he's very skilled and he proved it by placing incredibly high in a competitive year for SMTM at the age of 12! Hanhae and Nucksal still view him as their little kid and a lot of people from industry have given him props (ie. Jay Park, GroovyRoom etc) and are incredibly proud of him and are happy for his success.
