They're all super awesome! Everyone probably has different opinions, but I am forever SM biased cuz most of my fav groups are in there. Also, I know how everyone keeps on saying SM artists only have looks with no talents and stuff, but that's not true, most of them are super talented, like vocals: Taeyeon, Yesung, Kyuhyun, Ryeowook, Luna, Changmin, Jonghyun, Baekhyun, DO, Chen... They're some of the best singers in Korea. Also dancing wise, like Taemin, Eunhyuk, Hyoyeon, BoA, Yunho, Kai, Lay... They're also some of the best dancer in Korea. Also multi-talented ones, like Sungmin, Donghae, Key, Taemin, Seohyun, Xiumin, Luhan, Henry, Luna... They're seriously good at anything. I admit, they're a bit lacking in rapping honestly. Well anyways, they also have great personalities, they're super funny, nice, hard-working... They're company doesn't treat them the best, but they're determination and hard work have gotten them this far and I'm super proud of them!!! And they love each other like family!

So they have talent, looks and personalities, so that's why I love them to pieces!!!

If you're wondering, YG comes in 2nd! They're such talented kids! And they're music is super unique! Ya just gotta love them!

YG groups seems to be more close and hang around each other a lot, they're more like a family

JYP has some really cool group with excellent language in terms of marketing such as chinese and japanese and english

SME is probably has the most popular groups such as snsd, they have like obsessions with dancing in closed rooms though, so their productions are usually modern and futuristic, they are all about dancing and random costumes

Imma be UNBIASED with this one. Based on my own observation these 3 are the top 3 labels in South Korea for a reason. They have one of the best strategies when it comes to debuting their idols and their marketing skills for these idols are above average than the others.

As to your question of which one is better, is a really vague question. On which level are you trying to compare the three labels anyway? Because these 3 labels have their own advantages and disadvantages. And no, I'm not going for the simple-minded answer as "I'm an SME stan, I pick them" or "I love YG Family"

There was once a music critic that actually described the 3 big labels into schools:

YGE, for him, is like a private art school, where the principal (CEO) takes care of his students (idols/trainees)-- by monitoring their specialty and molding them into that area to make them even better at it. Hence why most YGE idols are either composers/ song writers, producers, etc of their own music.

SME was described as a military school. Where the head (CEO) makes sure that everything is PERFECT and FLAWLESS from the moment you get in (trainee) til the day you become a soldier (idol). Which is why, SME idols are usually the most intricate when it comes to their choreography, stuff like that. Okay, believe me or not, but SME has hired probably the best choreographers because most of their stuff are really good and quite polished when debuting/comeback. Unlike other boybands who dances like crap and have crappy choreographies.

JYPE, as described by him, was like a home school. Where the students (idols/trainees) gets to enlightened by the things they want to learn about the music industry by JYP himself.

So the question as to which one is better depends on YOUR perspective and not from OUR perspective. If you feel like you adore more JYPE idols more then that is your call. But you can never really say which one is better than the other because these 3 agencies are the reason why you were into Kpop in the first place.

i also think there all good but heres are a few points about eatch.

JYP- good music, catchy songs, doesnt have a overflow of artist and rookie groups, they dont seem super close but they are free to talk to other companies (sme yg..;etc) by the looks of it. also i love hearing 'JYP' at the start of a song lol.

SME- good music catchy, poppy songs. has alot of rookie groups and dont always spend much time on there older ones )such as super junior) what i mean is superjunior often repeative music videos of standing in rooms because they know people will watch it no matter what while rookies get plots and things. but SME also has more great artists in my opinion then the others lie snsd super junior tvxq shinee and so on. also they seem to get along well and collaborate alot within and outside the company also they appear in numerous variety shows and so on. but quite manufactured

YG- creative good songs, Psy lol, usually more edgy and fierce doesnt really do the aegyo cutesy stuff. original also less manufactured alot of the artist wrtie there own songs. but although the seem to be very cose with one another they dont often talk with people from other companies. also dont appear on tv as much doing the variety shows and things ( i like to see them on variety shows to get to know ther epersonailty) especially 2ne1 seems to never be on them. but they are great :) also prepares rookies well like lee hi.

i love yg !
