Woah, I'm super late on this but I finally saw the Japanese Genie and I have to say after watching them both I definitely prefer the Korean video but I agree with Tamatron and like the Japanese lyrics better.
The disco club Tae, Fany, and Sunny are in in the Korean video totally makes my day!
And it's not complete for me without Sunny doing that camera-push-walk-away thing at the end.
(I wish I had a gif of that)
@CKD I didn't see a Soowink but she did have that SooPOINT! which was almost as badass.
And unless I'm crazy I think she has more screen time in the Korean video, more closeups and stuff.
Hyo's points at like 2:01 are pretty awesome too.
