Personal preference would be the key, as WTFH Says, a lot depends on your eyes and how they handle light.
For me, I prefer the Smith I/O Goggles
, Review here and still use my Smith Phenom Turbo Fan Goggle
on deep snow days.
The lens I keep in the Smith I/O is the ignitor lens.
Here's a story about how good the ignitor lens is in flat light.
I have a friend who always buys cheap goggles, and always complained about his vision.
One day I loaned him my goggles for a couple runs and he saw the difference. But he refused to spring the $$ to buy a pair of goggles with that lens.
A few weeks later, when spring sales were on at the mountain ski shop, he asked me to go into the shop and help him find some cheap goggles that would work for him in flat light.
We walk into the shop and I ask the guy which goggles he has with lens' that are good for flat light, to which the guy (noticing my goggles) says "Better than the lens you have in those? There isn't one"
My friend tried on several pair of goggles with different lens' and eventually let the moths fly out of his wallet to buy the Smith I/O. His "go to" lens is the ignitor, just like me.
