My guess is that for buffalos it is smarter to travel against the storm while for cows it makes more sense to travel with the storm as that's what they have evolved for.Buffalo travel and head against the direction of a storm facing it whereas cows go with the storm in the same direction.
Which is smarter? Although articles suggest or say the buffalo is as they may spend less time in the storm by doing that, I would argue the stress or extra pain of dealing with the storm elements head on at their faces and not being able to see as well is not worth any very short amount of time saved dealing with the storm by heading against those elements.
