I would advise you to look for a box which has a Mali T820 graphics processor with 3gb of ram, 32gb rom and supports HD UHD HDR recording. The more it supports the better whether you need it or not. MyGica has always had issues when it comes to their software as they like to promote their boxes with various features and when the rubber meets the road, they come up short on the features that actually work as they envisioned they would. I was going to buy one of their latest boxes until it was not going to come with some of the features they stated during their promotion.
P.S. You can download and install Kodi on any box with Android 5.1 or higher. Try and get a box with 7.0 or higher .... with root if possible.
