Chromecast 2

• Google came with a new design for Chromecast 2, with a much better antenna (802.11ac) and perfect price ($35)
• Built in apps like HBO, Spotify, Youtube, Netflix (but all its competitors have these apps)
• Though aesthetic is much better, In my opinion it doesn't matter as it sits behind the Television
• Much improved casting from your phone, Laptop.. almost any devices with a cast option
• Also I liked that it doesn't have a remote, coz you can control from your phone
• Lacking power to play games

Roku 4

• Optical audio out (phew its old tech !!), 60 frames/sec, Roku OS7 
• The design of console is cool, but the remote seems out of date ( I would have done other way around as you use remote more than console)
