Bts and stray kids imo. No skip albums, lots of genres and s tier execution. Vocals, rap, ad-libs everything is perfect. Their performance and stage presence is great too so that's a plus. Best song? There's too many for these two.
Then I wanna add TXT, ateez and exo as well cuz I like their songs. For TXT they suit both dark and cute concepts so well. Ateez release rly rly good bops. Again they are all rounders. But I haven't explored eithers full discographies yet. So for txt I pick crown, can't you see me, and blue hour. And for ateez answer, twilight and say my name. For titles exo's monster n wolf is great. For bsides groove and I think artificial love was a bside or a single idk but it's good too.
