There are very very few carabiners with a truly rounded bar stock. The standard choice is the Petzl Attache. This carabiner too has a truly rounded bar at the basket making rope-feeding and Munters nice and smooth. Because the Petzl's rounded stock is thicker, it would feed rope at a more gradual curve than this one. If you don't mind the 21kN closed gate strength, this is a fabulous carabiner. I can't imagine anyone reaching 21kN of force if any biner is used correctly. The overall dimensions this biner is similar to the Petzl Attache.
