i used to like Wonder girls!! but they once came to Idol show with Super Junior H,, and they weren't interesting at all!! they were all shy and girly,, though their songs are really good!! but SNSD are much better!!!

I like SNSD (Girls Generation) better than Wonder Girls, but T-ara is my favorite girlgroup of all.

obviously its GIRLS GENERATION!!!!!!!!!!

hmm I like both. I think each group has their flaw, some members cant sing and some cant dance. LOL @ people disliking SNSD cause of there number, seriously?

singing: SNSD (Watch it I honestly dont think Wonder Girls are THAT great at singing (live) http://www.youtube.com/watch?v=1qqBztccXbY )
Dancing: tie
Rapping: definitely Wonder Girls
Prettiness: both pretty but I say SNSD wonderfuls who call them all plastics, not all of them had plastic surgery and its not like no WG member had plastic surgery
Variety show: SNSD I find them alot more funny esp. Sunny and Yuri on invincible youth

girls generation

Bahh, if I had to pick one, I'd pick WG. SNSD is annoying and I don't like their songs, now they always go for that 50-60s style, not really my thing.

Neither of them are my favourites, but I prefer Girls Generation over Wonder Girls.

This isn't really specific question, because you have to take into account each groups individual impact on the American music market, the korean music market, the European market etc. As well as the album sales, fan club size, entertainment companies.
Now I don't think this is extremely accurate in saying which is better overall, however perhaps you can rephrase it by saying "in your opinion..."
(lol sorry if i'm a troll. it's just somewhat annoying to see all the shallow comparisons with no evidence to back it up--not necessarily here but on other sites)

even though same type of music same random groups of girls dancing like awesome people
i just cant stand wonder girls

Girls' Generation, SNSD, Shoujo Jidai , So Nyeo Shi Dae. In my opinion, they are the better group. Why?

SNSD, with 9 members, learned to work together as a team and become one. They worked so hard to get to where they are now. All 9 girls share a close bond that unites them as SNSD. They managed to become number 1 for all their songs, do dozens of CF's, had their AMERICAN television network debut on Live! with Kelly and Late Show with David Letterman, completed successful dramas and variety/reality shows, and so much more. I mean what more can you ask for from a group that was just known for their singing? They have come a long way since their Into The New World era. I'm not hating on the Wondergirls either, I mean yes they were very successful and also broke into America. but I mean honestly, what ever happened to them since? Be My Baby was an awesome song I have to admit, but The Boys was even better. (: But this is all just coming from a SONE's point of view.

Honestly, I like both groups but when it comes to talent, likeability, and skills, SNSD will always have to come on top.

I don't like any of the Wonder Girl songs and the only member I like is Yubin. I'm not that fond of SNSD either (I think f(x) is the best ^-^) but I at least like them. They're more fun, from what I've seen in shows and I like a fair bit of their songs.

SNSD is my favorite as a group they are catchy K-POP and pretty however i voted Wonder Girls for musical scoring, song, and dance i really dig them

SNSD

Wonder Girls!

I choose SNSD!
