Personally, I prefer allkpop forum now. Few years ago, I was more active on reddit forum but the people there hate big popular groups especially Bts and Bp while I'm a huge fans of them. So, the bias was very obvious. And they have their favorite company to support and give tons of upvote for groups from that company when I was there. You said anything good about Bts and Bp got massive downvote while anything criticize them get many upvote. I don't really know how they treat the new groups there now but I heard they dislike Aespa too.
I think, I prefer allkpop forum now just because this site not as active as before and many trolls already left. Ngl, I do miss the time when more users active but now people just move to twitter and reddit.
