I always thought there was a leverage advantage to underlevers. One fellow who makes sidelevers told me they were superior because "your trigger hand doesn't leave the wrist" - I didn't know what he was talking about, but now I see that one could develop the quick method of reloading holding cartridges in the fore hand. Still doesn't make up for the ugliness. Oh yes, it might be easier if shooting from a bench to have a top or side lever. But I love the looks and ambidextrous nature of the underlever.
