For CE it is great. Looking forward to trying out a Ugoos box, but really wish they officially supported AndroidTV, can't really see the desire to use a tablet OS on a TV.

There are some really well supported Android TV OS images for the Ugoos devices available that are built upon existing, great Ugoos tablet Android OS Firmware. See the Freaktab forums (click)
@Sasvlad over there has increased the CoreELEC partition size to 3GB which should alleviate Ugoos Dual Boot Firmware storage space problems.

Standard AMLogic Android / CE - Dual Boot is much, much simpler and will be a lot more reliable. It's a well proven setup.

Do you have to rely on an android image provided by them? It’s a tablet OS isn’t it?

Can’t you install lineage OS which I believe is android TV?
