C2 or XU4

Hi im planing to refresh my sbc from C1+.

I wondering about these two.
Generally i want to use : Transmission / FTP / Kodi

Is XU4 - capable of 4K render ? ( it have HDMI 2.0 ? or 1.4a ? - i found few differens infos about it )

What u think will fit it more ?

I have both and think the C2 is better for Kodi. The 4K video (not that I’ve tried it) and x265 hardware decoding are great features. Does the job well, is cheaper, runs cooler and quieter.
