1st point to make with the T8V Smart TV box -
Don't believe all the bullshit Hype ! - Big numbers and Tech Specs are not everything.
If that T8V is a AMLogic S912 it will come with buggy Firmware - there are numerous well known issues posted all over these forums with S912 boxes regarding video output and Kodi compatibility. Not recommended at all.
The only decent S912 I have seen is the MINIX NEO U9-H and that is because it actually has bug fixes in its Firmware.
The S905X Vero 4K (OSMC) will crap all over the S912 T8V Smart TV box so far as near bug free Kodi compatibility is concerned - it really is no contest.
If the T8V is a AML S905 box then it will have better Gigabit Ethernet vs the 100M in the Vero 4K. BUT there is no HDR support that the Vero 4K has and Firmware and Kodi support will be inferior.
The Vero 4K also uses a nice integrated Wireless remote and it has AC WiFi. It really has all the bells and whistles needed.
