Well I don't watch any of them, but I have browsed Twitch and most of those you mention look like they're in a dank basement where weirdos collect weirdo things... Goth and Bro are annoying as -blam!-, but at least their broadcast are clean. Sure you're watching for the game, but something about a dude just sitting in his sweats in a gaming chair with a single incandescent bulb swaying overhead and a grainy web cam makes me shudder...
