Yet another anon butting in on this discussion because this stuff is like crack to me, sorry. I always consider the difference between what someone values and what motivates them.
Hermione, especially 11-year-old Hermione, values booklearning and knowledge and smartness, and holds those values incredibly close to her heart. However, what motivates her is being not just right but righteous - even when she lacked social skills so it came off badly, her desire to follow rules or to help Neville find his lost toad for example were based off wanting to do The Right Thing. She values knowledge because smart people save the world and do great things to help people. Hence, she's a Gryffindor.
On the other side, Luna is super loyal and brave and she definitely values those traits (see: the 'friends' mural) but her driving force will always be knowledge. Bravery is a tool to find out new things. Being loyal to your friends is right and good because they are your partners in the world and you learn together and that makes learning even better. Hence, she's a Ravenclaw.
Prompto values friendship. Prompto values bravery. Prompto values proving himself. Which one motivates him, is the question. Consciously or unconsciously.
Does he value friendship because it gives him a sense of purpose and support, and/or something positive to push himself forward towards? Then he's probably a Slytherin. Does he value it because they help him be brave, and being brave and doing good in the world is the most important thing? Then he's probably a Gryffindor. In both cases, he uses his friendships as personal motivation (which is not to say he doesn't care about his friends, or that he's selfish!! He does and he isn't, whatever house you place him in!).
Does he value it above all else - is he brave only as a tool to help protect his friends? Does he want to improve himself and his life solely as a way to support his friends? If the other things he values are most valuable as tools to support his loyalties, he's probably a Hufflepuff. (Again, this is not to say that only Hufflepuffs love their friends!! All houses love their friends!!!! Hufflepuffs are not The Only House For People With Healthy Friendships!!!! It is perfectly normal for your friends to be a support system and motivating factor and does not mean that you wouldn't kick ass for them at a moment's notice!!!)
I'd personally argue, for example, that Ignis is a Hufflepuff rather than a Ravenclaw for this reason. In my opinion, while he values intelligence hugely, in all its forms, it isn't his motivating factor - it supports his loyalty, and that is the biggest reason it has value to him. But this is still all based on interpretation, hence the three different Prompto interpretations above, so there's no right or wrong answer, just the one that feels most accurate to your interpretation of the character, imo. If you can support it, I can get behind just about any Sorting for any character.
