Here's how I see it. Warlocks can do neat space magic. But they are all scholars and when you think about it they are basically the nerds and college professors of destiny. Titans are battle tacticians and are the commanders and the "lets get stuff done" type of people. What they stand for is cool but they aren't very interesting themselves. Hunters aren't SUPER important and don't have lots of interesting background or ideologies. But in my opinion are the "coolest" type of guardians. I mean come on, they have cloaks, gas masks, use throwing knives, and roam the wilderness. They are basically Han Solo, Indiana Jones, and Bear Grills combined to form one cool motherf****r.
