Ok I could be totally wrong about it. I.O.I and X1 doesn't count in this scenario because they are short lived so it's down to Wanna One vs IZ*ONE. W1 sold more, had more concerts, probably have a larger fanbase than IZ*ONE during their time as W1.
But somehow post IZ*ONE artists seem to be doing better than W1 artists. Comparing the latest sale numbers (and I could be wrong and not sure if I missed out anyone) its
Daniel>Yena>Yuri>Seongwu>Eunbi>every other W1 member
Group sales wise, it's IVE>LE SSERAFIM>NUEST>AB6IX>CIX
I mean shouldn't BG sales be higher than GG sales in general? All groups have "produce advantage" if you want to call it that, but even with the "BG has fandom" narrative, GGs are blowing them out of the water in sales. Don't even talk about charting. Daniel is the one that is surpassing all the other W1 members.
Not only that, for groups, IVE and LE SSERAFIM surpassed IZ*ONE, while every other post W1 group is selling like 1/10 of W1.
People say GP is fickle blah blah whatever then why are W1 members sales decreasing across the years? Is there no loyalty among the fans? Are WIZ*ONEs more loyal in supporting their faves?
