Chromecast streaming stinks, anyone using Android TV?

I’m looking for a Android TV box so I can stream DC Universe. I have android phone and tablet and the streaming of DC Universe is horrible . So I want to get a Android TV to work around that and maybe play some games on the TV.

The Questions:

  1. anyone using a Android TV device? and which one?

  2. Will the android TV’s use any app from the google play store?

Thanks in advance!

My android phone and tablet app works perfectly including streaming. I have a Roku and that works great too
