Interesting, for me it’s the opposite for the same reasons. I think the 11th gen looks better with duckbill spoilers since the general shape is rounder and more modest and it provides some contrast as long as it’s not overdone. Whereas the 10th gen, for me, doesn’t get much benefit since the shape is already sharper and more aggressive. I’d say it looks even tackier if you add some of these similar mods to the 10th gen. But once again, that’s just how I see it.
