In terms of holding up both should be be able to handle that volume of shells successfully. I do not believe one action is uniquely superior to other in terms of durability.
In terms of aesthetics it could argued one looks better than the other, or more importantly is sculpted and balanced better than the other. Many might argue the Browning a better balanced gun, but balance and handling while in some respects definable in some respects they are not.
Put another way, each of us picks up a gun, mounts it, swings it, and gets feedback unique to ourselves. So a browning I swing that feels better than a winchester may feel the exact opposite to my brother based on life experience and what we like.
To further complicate things different guns of the same specs will at time feel completely different.
My bottomline is go out find a candidate, pick it up, if it feels right, see it you can shoot a round, if that turns out well buy it.
