As far as patterning goes, I would be astonished if you could prove a significant difference. Words like "flat" and "even" have very little place in describing a pattern; from any gun. Cool, unique, etc.? Yep. Pattern? Nope. I know of only one guy who can really manage light, low swing effort (low MOI) guns. I strongly advise shooting a borrowed gun long enough to tell if you can really manage such guns before buy.
