The design of the cog was mentioned in 6 of the 25 posts on the first page.
"The potential quality of the product" is ambiguous, but it seems agreed that the level hub is materially overbuilt and they feel good out of the box. I am talking particularly about the longevity of a cog because I feel the longevity of a hub is so long that its almost unimportant in decision of which hub to buy. This is my rant. You are not buying a new way of life, its just one hub. Even if its twice as expensive, its going to last you longer than your memory of the money so its unimportant. If you want to talk about the feel of a newly built ride, great. If you want to talk about durability, great. If you want to be snarky, carry on.
