[XBox Streaming] Twitch or Mixer?

Hello,

I would like to stream live for XBox One only, what would be the prefered method to eventually get a spot in the front page?

Twitch? or Mixer?

I have a "PC" account that I've played with since September 2012-3 (Can't recall exactly who pays attention to that anyways lol). Should I just use that instead? I'd like to make PoE XBoxOne guides, tips, videos etc...

I'm trying to start off as strong as I can. Your input is greatly appreciated.
