its all preference man... some big mountain/backcountry riders will like a stiffer boot because it gives better response and they can charge harder in it while say park riders will like a softer boot because they are more comfortable and would like it to be able to flex to do sick butters and presses and grabs and stuff but thts not to say some backcountry freestyle guys like jp wouldnt want a softer boot if they are hiking a b.c. booter and are getting some sick tricks they want the flex
