Ever since I tried Serengeti sunglasses with the rose/amber/whatever color they are "drivers" lenses, maybe 15 or so years ago, I've worn almost nothing since. I do have one pair that has grey/green lenses, which I occasionally wear, typically only on cloudy days (we don't have many of those in Tucson). If you're used to the typical grey lenses, it'll definitely seem weird going to amber/rose/bronze colored lenses, but when you're used to them and take them off and/or switch to grey lenses, suddenly the world seems so bland, drab, and dull.
Serengeti's also all have their "photochromatic" technology. Meaning the brighter it is the darker they get. The change is subtle, not even remotely as dramatic as "Transition" eyeglass lenses. But it does help when you're going from inside to outside or from out to in.
I also like that Serengeti's - at least the models that I've owned - use glass instead of plastic lenses. I stick with simple shapes, thin frames, etc. I can't pull off the Wayfarer style, and I feel like a douche wearing aviators or wraparounds. My favorite pair is the "Getaway" (center, 2nd from top). They were the first that fit me without modification. I've worn several through about 15 years or so, and they've only been replaced because of accidents, not because they "wore out" or anything (no big scratches, but lost 2 pairs, stepped on one, a lens slipped out and broke from one because the screw got loose, and I endo'd on my bike and faceplanted wearing another). Unfortunately they've long been discontinued so I'm constantly trolling eBay looking for NOS or gently used ones. None of their current models interest me at all, but that's just me.
The only other brand I've considered is Maui Jim. I've heard nothing but good about them, they use glass in some of their models, and their amber/rose lenses look like they're not dissimilar to Serengeti.
