DBM
Pros: easy to reload, you can keep loaded ammo separate from rifle, but can "top up" quickly while still staying within game laws, you can reload different ammo types quickly.
hinged floorplate: cheaper, simple, no magazine to lose, fits flush make rifle handier for carry or for offhand shooting, nothing to snag when moving through brush
For stand hunting, I'd go DBM. If you're carrying it around through brush, hinged floorplate. I do the latter and have little need for the other features of the DBM, so I don't have any bolt DBMs.
