I think most people who are taking sides here are basing the entire argument on who they think is funnier.

Just as the average late night watching yokel doesn't like Conan's material (and I don't understand how they've ever liked Dave's nonsense), the average Internet douchebag has no idea Leno was one of the best comics anyone's ever seen.

They just know what they've seen at 10:30 and 12:00 since they've been kids, and you know what they've seen? A big chin motherfucker who told boring jokes. That's all he is to them, and now, he's also the asshole who took away Conan's shot at being the Tonight Show host.

So, if you want people to look at this reasonably, you're missing the point; they're comedians, and one is clearly funnier on a nightly basis than the other.
