Max, Three answers: The best clarity, versatility, great fit and lens selection.
if you don't mind a single lens, the Race model from Uvex (L Vonns' Goggle) has great optical clarity that few if any dual lens goggles can match. It also has a impregnated antifog treatment. (clarity)
For a dual lens non sperical I use a Bolle with the photochromatic lens and find it great 98% of the time. (versatility)
For a spherical, I like the better smith models with a lens color appropriate to where you live/ski. (fit lens selection, quality)
Also, ask Harald about the Fuxi goggles his friend produces.
there you go, a quiver of goggles to match many of our ski collections
