Should I swap my Raspeberry Pi for a Xiaomi mi Box 3rd Gen with 4K

[MrT]

Xiaomi mi Box 3rd Gen with 4K Miracast and more.
As anybody got one of these?
I am using a Raspberry Pi at the moment,but i'm getting fed up of the lagging,crashing and other problems. Recently I'm having buffering problems with everything I try to watch, or it will not play at all.
I am thinking of changing to the Xiaomi mi Box, I have found a good offer for one.
Any thoughts??
Thanks

i've got a Mibox pro, since the latest firmware, no video acceleration with XBMC and no Root available ...
