I have had both the welded and screwed type. Have had no problems with either. But if I would reccomend the screwed type as stated by Jeff. In fact Jeff has done all of my Unitizing 
He does a outstanding job. As far as authentic looking? The screwed method is more authentic looking as the screws are on the inside. The welded method shows the weld on the exterior. That was my prime reason for having Jeff do mine was due to the unchanged look that the screwed method had and the fact that I didn't have to worry about any warpage.
