I'm taking all things into consideration and trying my best to not be biased, even though Wheein is my bias. Being the least talented in MMM is hard because everyone is so great, and I'm just really nit picking here just for the hell of it haha.
Moonbyul; she’s my least bias. Her vocal’s the weakest, however she’s a great dancer and performer. Good rapper as well. Being the weakest vocalist in MMM shouldn’t be as bad as it sounds, because have you heard the other 3? lol. If any other idol is in MMM, will they be confident enough of their vocal abilities? She has decent success with her YT channel. If she went on more variety shows, I am sure she would do just fine. She's a great interviewer. She worked crazy hard and got out of her comfort zone to be a vocalist and got praised for it. Out of the male dominance KOMCA credit, she is the sole female within the top 20-25 at 115+ credits, that’s just fucking insane.
Solar; she’s talented in almost every way. She has been a judge on multiple shows. Her YT is very successful. She tries hard in variety shows and her personality and work ethic is amazing. She is the second best vocalist in MMM IMO. She’s also a good performer too. She has about 40ish KOMCA credits dating back to MMM early days. She embodied hard working and a person that isn’t afraid to try new things. It’s very admirable.
Hwasa; second best vocal tone, third best vocalist. Absolutely phenomenal performer. She really enjoys the music, she feels the music, her charisma is amazing, she is the stage. I don’t think there is a song that she cannot sing. She makes any song into her own. She wrote a lot for MMM early days, and also her own albums too. She does quite well in variety. She was recognized by Lee Sun Hee, and had the privilege of going on a country tour with the legends on Dancing Queen On The Roads, who does that?
Wheein; great dancer, best vocalist, best vocal tone. Her YT is evenly matched with Moonbuyl. She hasn’t appeared much in variety and I cannot gauge how she interacts with other idols. Because this can be used as a way to speculate how well you’ll do in a variety show. She has the least KOMCA credits AFAIK. Because MMM are so talented and boast such an impressive resume, I would need to list these things to actually see who’s the ‘least’ talented. And by saying the least talented here- it all boils down to just “she doesn’t have as much writing credits” honestly lol. Even myself find that hard to type out, but it’s fun to discuss such things.
There’s almost nothing that each member does that the other cannot do, albeit a member can’t really excel at someone’s ‘best’, but they'll do a good job enough that you’ll say “if she was in another group, she would kill”.
