It depends on what area are you talking about, pvp or pve. For pvp unless bungie really put a tourney so that those people will go face to face more than 2x in a row then you can clearly say who is the best. Almost all of them can pub stomp nubs. Eg. Like me. The only way to find out is make them battle each other to the top. Except broman. He's way too low to be compared to the others listed.
