I edited the pole so people can change their votes if they like caving in to pier pressure.
It's a tough call but after thinking it over I did vote Twitch. While I Overall like the Hitbox UI better and it streams very well. I feel that Twitch is more responsive as it seems to sync up faster and stream past videos faster with less interruptions (at least for me). Also it is more established in terms of exposure.
I really do like hitbox though, so I could go for either one.
