Reliable 4k HDR TV box

Hi guys,
I want to buy a 4k HDR Tv box that would allow me to play most of the 4k (HDR) content that I can find. I searched through this forum but there are such different opinions , so, as I don’t have any way to get one for personal testing , I wanna ask you for some advice:

1) I was looking for the Himedia (q5/q10 pro) and the zidoo(x8/x9s) . Seems the majority prefers the zidoo ones(although I’ve read some pretty bad things about their support) so , 2 choices now: zidoo x8 or x9s.

2) The price difference between them is 40€, and it seems there’s not much difference in performance between the 2, just the 8gB vs 16 gB emmc.

What would you recommend? I’m willing to spend up to 150€, in a reliable box with support , and especially, not many bugs displaying the pictures.

Regards
