I have a pair of Kscopes and like them, I use them at night/flat light. They're inexpensive, don't fog up, and come with an extra yellow lens. The frames are nice and soft too.
I heard smith IOs are dope....and sheep seems to reinforce that.
I say, try them both on (if you can) and see which one works for you. If all things are pretty even but cost is a factor, get the Ashburys. Pretty good value.
If you'd take another suggestion, I'd like to also recommend Airblaster Airgoggles. They're my favorites. They don't fog no matter what stupid stuff I do with my goggles, they're comfy, SUPER durable (I treat goggles like shit) and are also inexpensive. The Baker lenses also don't lose their mirroring, if that's something you care about.
