I have MTM suits by both, from Harry Rosen, and prefer the Samuelsohn for the reasons above. The full canvassing makes the Sammy hold its shape better over time. In addition, Samuelsohn has more models to choose from, and I have found one with a great silhouette for me (the Todd, with relatively unpadded, roped shoulders and good waist suppression). In my experience, it was only about a 10-15% upcharge versus Coppley, which I think is well worth it at that price level.
