BlueNux

Remember that both skates are going to have different fits; the 2N has a wider boot with more volume. 

Also, the 2S isn't the top of the line, it's one step down. 

 

Aside from that here are some quick differences: 

-different liners (although both are still what you'd find on a high-end skate)

-Flexible tendon guard on the 2S (some people like it; some people hate it)

-Apparently "Carbon curv" on the 2S, not on the 2N, I'm not sure if that's a major difference. 

-3-piece tongue on the 2S, 2-piece tongue on the 2N, both 48 oz. 

 

I also heard in a video that the 2S outsole has some nylon in it and it isn't full composite. I'm guessing the 2N likely is. 

Just to make a few corrections. The 2S is not carbon Curv, which is the new Curv only used in the 2S Pro.

The 2S is a hybrid of last generation's S180 and S190. The most important part of the skate - the quarter - is made of regular Curv and is more similar in stiffness and material to the S180. The S190 is stiffer than the 2S.

The 2S outsole is a non-vented fully composite outsole. The nylon you're mentioning is the midsole, which is the part of the boot you see if you remove the insoles from the skates.

In terms of features, the 2S is rather disappointing, especially when compared to what's offered by CCM. However, the fit of the new Supremes are awesome; the ridiculous heel lock and cushy padding are reasons enough to consider them. They changed the liner, thickness and location of the foam padding, and some fit-related stuff this year that makes them feel noticeably different from the previous Supreme generation.
