Here comes the brand wars, you can ask 40 different people and can get up 30 different devices.
All I can do is give you the up's and downs of the devices I have.
Remix
Remix Mini From
http://www.jide.com/mini With an
Rii Air Mouse
Pro's Have a PC look and feel, runs Kodi like a dream and plays most media without problems. I have the 2Gig model that seems a hell of a lot more responsive than the Mygica in the lounge.
Con's I find myself constantly turning off the mouse function on the remote as the nav bar appears in Kodi when you hit the edges. Does not output 4K, can decode but only outputs to 1080p
Need to install Play Store manually (even if its a simple 1 click step, its one more than what should be needed)
MYGica
MyGica ATV582 from
http://mygica.com/Enjoy-TV/ATV582.html
Pro's Does 4k output and comes rooted, with Google Play and Kodi Pre-installed.
Showmax & Netflix works like a dream (Comes with both pre installed)
Con's Is just good for media, using it for anything else is cumbersome to almost impossible. Navigating Showmax can sometime lead to head aches and unneeded stress but that is more the app than the devices problem.
I have the Remix in my bedroom and Mygica in the lounge, both streaming from the media server (via Kodi) in the study with little to no hic-ups. What I did find is I can not stream both on WiFi at the same time, so did go over to Ethernet.
