I'm sure Peardian could explain this better, but yeah programs like Blender, 3DS Max, Cinema 4D Studio (all of which generally being some of the most popular and most used model programs) and etc. can load .DAE, plus DAE keeps the original bone and rigging data which is invaluable to the end users. .OBJ doesn't support bones, plus when you load OBJs you have to apply the textures yourself and so on.
Ultimately the .DAE is more useful overall but for those people who can't use that format for whatever reason (there shouldn't be too many people who can't, but it's always good for your submission to be usable for everyone in most every scenario), you have the .OBJ too, which they can rig and texture themselves if need be.
Anyhow hope that answers your question. That extra format may seem useless to you but in the end it could actually end up being the most useful thing to those who use it.
