I see no point in comparing two things that are the same. Thats Like me saying "Which is better Hot cheetos or hot cheetos?" It makes no sense to do it that way when you can say "Hot cheetos or Doritos" which would be more logical because you're comparing two different things.
I think this is a problem in many communities especially with Kpop. We think "you like black pink over twice I hate you go die." Or we would rather avoid the conversation. I enjoy striking dialogue because its interesting and can open your eyes to new things. So let me rephrase...
Why are you so defensive? It's ok. It makes sense to compare things that are similar. Like ioi and twice. Who's better? Comparing two completely different things isn't good. It's more like comparing cupcakes vs cheetos. Comparing similar things is like comparing two diffent types of chips
