I wear Serengetti when flying and Oakleys on the ground.
I prefer the colour tint in the Serengettis and find it easier to pick out traffic with them (probably just my imagination though!)
The Oakleys are A-Wire and have grey lenses which I like when out and about. I might buy an amber tinted pair like the Serengettis in the future though as I find them a little heavy on the nose after a while whereas I can wear the Oakleys all day.
