Is Stray Kids the most successful JYP group ever?

sales and money wise yes, but streams name recognition wise twice is bigger

If you mean by bringing more money Skz, since they sell more albums and are self produced.

If you mean by Impact - then Twice

Quote from Yama-Chan

I mean success.

Twice still has an edge, but Skz is coming for that spot very soon.

Im glad that between attending kcon you can still find time to sow dissent between jyp fandoms

I'm not a troll; I'm just a contrarian.

Fancy word for a troll who actually knows how to troll

If they are not yet, they will be in the future.

Twice and Stray Kids

Followed by Day6

JYP said it himself

I voted on the poll.

By name recognition I'd say g.o.d has the edge. They weren't called "the nation's group" for nothing.

From wiki

Quote

g.o.d was the first boy band to be dubbed "the nation's group" (Korean: 국민그룹; RR: Gukmin geurup), a sobriquet popularized by the media and cultural commentators due to their appeal to not only the teenage demographic, but across a much broader age demographic compared to their contemporaries.^{[139][12][13][62][66][140]} In contrast to their contemporaries, who were primarily targeting a teenage audience, they were known as the boy band which "appealed to both teenagers and their parents"^{[13][31][129]} and "rose beyond its status as an idol group to be loved by people of all ages."^[141]

the issue is how one defines "success"

and if it's monetary I think I would argue twice over SKZ for now - that might change moving forward
