Aespa have been active for less than 2 years and Girls did just 10k less units than FOL on BB200 with the same ranking (#3). Girls is also just a mini with just 4 new songs while FOL had like 18 songs and only did 5k more streaming units.
I'm a casual listener of both groups and don't really prefer one over the other, but those saying Aespa will never reach Twice level in the US are dumb. Sure, Aespa might never chart on BB100, but neither can Twice with any song that's not The Feels, which was an anomaly not the norm for them. I'm sure at 7 years old with more western promotions and an actually good English single Aespa could also chart on BB100.
Twice's main strengths in the US are BB200 and touring power. Aespa can 100% get there too, they are practically already there in terms of sales
