The 9 flyknit lows had better GR releases (Beethovens, Moonwalkers, Thrillers). Besides the Multicolors and the Mamba Moments, the standard Grey and Black options were meh.
I didn't care too much for the weave pattern, and the spray paint looked terrible.
The 10 flyknit lows were the opposite. The GR colors were meh and the iD options were great. The standard grey looks much better than the 9. Even the painted pairs looked great. Besides the painted medial fiasco with the Multicolors, I think the 10s were great in my opinion
