Yeah, and a lot of that is personal preference. For example, I've pointed out before that I actually LIKE the Dark side gears better than the Light side ones - personal preference. They all have the same stats, and as far as looks go, people like what they like.
You say Light has a numbers advantage and then in the same breath you say Dark has better equipped, better skilled players. If that's the case, the two advantages should even each other out.
