Welp they have some public recognition for sure but I disagree, their fandom is bigger than twice's at least nowadays. This is very clear when you see their melon streams vs unique listeners compared to other ggs.
not sure if you are overestimating or i'm underestimating Gidle korean fanbase lol but i have a hard time to believe they have a big enough fandom to get them in top 10 when even boy groups fandoms can't do it, i guess we will see
edit: i forget to say that i highly like highly doubt Gidle have a bigger korean fandom than Twice
