Digital performance not only locally but also internationally plays a big or important role in your opinion to consider a group as a top one?
Honestly I do think so because digital performance reflects the impact of the group among general public the recognition, you can’t have a hit song or a song charting for so long with fandom alone that’s impossible.
Boygroups have such strong physical sales that can overpower everything else, hence why so many of them can be consider as top groups even tho their digitals are terrible.
