In terms of total career stats:
Touring : Blackpink and its not even close (They make the most money in their career as a result)
Album Sales: Twice and its not even close
International Streams, Charting: Blackpink and its not even close ( YT, Spotify is at least 4.5 Billion gap, Blackpink has #1s in charts all over Asia and they chart better in Europe and NA as well, plus they are basically #1 in China)
Korean Streams, Charting: Twice has about 10 hits in Korea, with 3 very big ones in TT, DTNA and Cheer Up, Blackpink has about 9 hits with 3 very big ones in AIIYL/LSG, D4 and HYLT ( so its close but Twice edges it), SNSD has some really really iconic hits but overall they are way more well known for their recognition than digital power and NewJeans is too young
Would say because of this Blackpink edges it as the most successful k gg of the 4 and of all time. Personally I dont really care about brand reputation, popularity, international/korea impact and everything else but if those are added then it would just be more points for why Blackpink is #1
