We should all agree that your regulator in your mouth, anytime you're in the water, is probably the best option. But like mentioned above, for those situations where you are either out of air, have a malfunction, or are conserving air, the snorkel is the next best bet.
Sure, in good conditions, you would be fine with your mask on, kicking away, no breathing apparatus involved.
I personally prefer to keep my face in the water, looking around, whenever I am on the surface, so a snorkel is a must for me.
On a side note, I have seen someone try and go descend with the snorkel in their mouth instead of the reg, it's quite humorous.
