Ok, first and FOREMOST! I did not create this thread to FITE anyone 
(just stating fat facts 
) And this can also apply to BIG 3 supremacist. I can't stand how most baby kpop fans tends to forget and skip the era way before their biases.
ANYWAYSSS, here are the things I realized after stanning groups outside SM Ent:
1. BIG THREE GROUPS AREN'T THE ONLY GROUPS THAT MATTERS
- Like, I mean.. right?! back in 2009, I really only listened to SNSD and SNSD only. But then I watched Invincible Youth in KBS World.. and.. I discovered gems like SECRET, T-ARA, KARA and freaking B.E.G (which is an ICONIC group btw), NONETHELESS, There are other groups out there that Kpop can offer so give them a chance!
(here's a funny moment from IY, but the quality is cursed ugh)
2. BIG THREE doesn't always produce quality songs than any other companies (DUHH)
- I remember BEAST producing quality title tracks together along with SHINee and Big Bang back then and even enjoying most them. Same goes to B.A.P x EXO back in 2012-2013 (only if TS didn't fuck up.. they'll prob be at BTS level today, yup, I said it 
) They do, for the MOST part does produce quality songs BUT there are a ton more ICONIC songs from different labels that contributed and made KPOP what it is now.
(here are some ICONIC Songs from other labels)
3. THOSE ARE SOME OVERRATED MAIN VOCALISTS AND MAIN DANCERS 
- I remember people coming for XXX throat for saying Big 3 main dancers/vocalists aren't everything. I mean.. THEY ARE NOT, get over it. Obviously, when you have dancers like these:
AND Main Vocalists like these:
THERE's PART 2 but I'm afraid to die from Big 3 stans.. 
(don't.. slander me 
I'm still pretty much an SM stan, kinda )
