Compared to company groups. I love SM groups, I've always listened to them since I started consuming K-pop, but SM solo artists can't get my attention as much as groups do. As an example I can mention BLACKPINK, I love both BLACKPINK's solo works, there are many that I listened to a lot, but compared to Red Velvet's solo works (I'm a reveluv) I didn't like it that much. So I feel a little frustrated that I haven't been able to consume SM artists' solo works in the same way that I consume groups.
Remembering that this is just a personal opinion and not an absolute truth
