NFM Has subcontracted the manufacture of their Extreme Cold Weather Jackets to Carinthia themselves, so they feature the same G-loft filling - the jacket is just of a better and more thought-out design (imo).
The NFM jacket does not have pit-zips. Nor does it have a pocket on the lower left arm.
Other than that, it has the same and more features than the ECIG. It is also marginally lighter, at roughly 1200grams (if memory serves).
For me, it was an extremely easy choice to go for the NFM ECWJ.
