it depends what kind of comp and how the trick is thrown, if i was a judge and saw a good bflip and a good switch 5, i think i would choose the switch 5, once someone starts riding switch, everyone goes, "o my god! hes riding backwards!", but a backflip is always crazy, if the judges know a lot about freeskiing and how much harder a switch 5 is than a backflip, the switch 5 would win
