Curtis buys "the best" things so that the things he owns reflect back an ethos of caring about the things you build, making choices deliberately and carefully, and being able to rely completely on what one owns.
Moxie buys "the worst" things so that the things he owns reflect back an ethos of focusing on people and experiences over material acquisition, and having a life of serendipity and unexpected but gratifying hardship.
Neither of those are wrong, but the mistake is to believe that the items themselves carry that connotation. They don't. Curtis could carefully select a perfect spoon from the 50 cent thrift store spoon bin and that spoon would still be "the best" and reflect his values. Moxie could win the lottery, buy a yacht, and run it into a jetty without a care in the world and that yacht would be "the worst" according to his principles.
Conversely, Curtis could feel obliged to use some $1,000 parachute material daypack perfectly designed to carry his equisitely selected pen and paper when what he feels like right then is grabbing the pretty purple bag because he is an unwitting slave to having his stuff reflect his higher principles. And, likewise, Moxie might refuse to be caught dead behind the wheel of a BMW even though it turns out he would love the experience of roadtripping it in with friends and the way it feels cruising down the Interstate at night because having it would mean "selling out".
Curtis and Moxie can still both end up slaves to their things because they've given them totemic power without realizing it.
The trick is to realize that we can choose to apply meaning to things, or not, and we can give and take it when we want.
