Surfer Shades or Aviators

I'm going on a cruise in four hours and have lost my sunglasses (surfer shades) (pic below). .

I have to buy new shades. . Do I stick with the surfer shades (which I've worn since 1985) or go with the Aviators? I have about 2 hours to make a decision. .

If you say Aviators, then what's a good brand at a reasonable price ($100). .
