Sorry, I should have typed yongjun. That way i won't make mistakes. Btw whats the difference between weilong and chilong and sulong? (I hope they make talong or 大龙 next) (which means.big dragon)
The Weilong is considered top-of-the-line as far as cubes go (along with the Zhanchi).
Moyu makes the Weilong, while its parent company YJ makes both the Chilong and Sulong.
YJ is the budget/introductory brand, and Moyu is its high-end brand.
Analogy:
YJ would be like Chevrolet or Honda
Moyu would be like Cadillac or Acura
So the Weilong is in a different class from the Sulong and Chilong (despite the apparent similarity in their names).
The differences between the Sulong and Chilong are that the Chilong is a revision of the Sulong, with torpedoes added (anti-popping) and tracks on the edge pieces.
I should mention that I own a stickerless YJ Yulong and I absolutely love it. The Yulong is an adaptation of the Chilong that allows for stickerless versions to be made. I really like the quality of the plastic, which is better (in my opinion) than the quality of the plastic in the stickerless Zhanchis that I own. The stickerless Yulong is a very good cube for the money. In this one case at least I think that this is a budget cube but despite that it's also a very solid choice.
I should also mention however that I'm not sure a stickered Yulong would be as good. The plastic on my stickerless is extremely glossy and smooth, and I'm not sure that a standard black Yulong would feel the same, even though cube color shouldn't result in any differences.
