One thing is for sure, those are all well-proven designs and it's tough to wear ANY of them out. The wannabe engineer in me likes the Mossberg design better than the tilting bolt design because it allows the use of aluminum receivers and the barrels are a helluva lot easier to swap. One of the stiff points in all my Model 12s is the bolt tilt part, particularly when UN-locking the action.
