Ive used oring chains, xring chains, and zring chains of all major brands, who is has the best design. The DID Xring is the best on the market, even their oring is a mere match for other brands xring. Zring chains are [censored], the design of the ring just doesnt work very well.
Oring chains seal well, but they generate too much Friction heat and this aids in drying out the internal grease, thats why the xring in general, lasts longer, less friction. Add in the specific xring design adds to the life of the grease.
If you ever seen a chain in action on a motorcycle, it has horizontal and violent vertical forces which can break a sealing joint intermittantly, so chain sizing also comes into play for stability, to resist the flexing motions.
