I am partial to Coppertone Oil Free SPF 50 (minimum 30 if I can't find 50):

I like this bc it's NOT greasy at all, it works, it doesn't make me break out (acne or skin reaction) and it doesn't have that tell tale sunscreen smell. It can be hard to come by in the store (higher than SPF 15) and when I'm forced to use something else, I hate it. I should buy this in bulk as my husband and I go through many bottles a year.

It may not be the best or most natural but it is definitely my favorite. Frankly, "good" sunscreen is the one you'll actually use!
