I went to the website of noob/ZF comparison video, they have a useful thread as a reference for N/ZF/Gen comparison.

Myself is a noob v1 owner, and after looking at those pictures, ZF is not enough for me to upgrade because...
1. The hour markers are more polish and rounded on the edge of Noob's version which is more gen like, where ZF is sharp on the edge.
2. The bezel teeth noob is very very close to gen, but ZF looks off...looks weirdly off, not sure how to describe it.
However, ZF does have a few compelling upgrades, most noticeably the strap bar and the screw head!! It seems much stronger to hold than the noob one which I lost the screw head within days of wearing!! Also the outer layer on the dial of noob is race track pattern (that's how they described it in the comparison), where ZF is flat and hairline pattern, looks exactly like gen. Other than that, since I have the v1, my bezel numbers are close to gen so it's a tie. The bezel color is too minor I kinda just ignore it....
If they can fix all the flaws mentioned above, I will immediately buy the ZF BFF.....but until then, I will keep waiting and enjoy my v1! Thanks.
