hulu, netflix or amazon video?

Amazon video is really promising!
I love Netflix and how wide they are already with their shows and things... though I hate how it's different for each country... Surely, if they have the rights to the shows in one country, they can show them in others as well... Really unfair.
With regards to Amazon, if you get Prime, I'm sure you get video as well... so it's also nice to support Twitch streamers with the free subs you get
