So here in brazil i see some options avaiable Tanix Tx, Mx series and xiaomi.
Iam complete new on hardware but i know everything about apps, video streaming and other stuff.
The problem is: Tanix tx3 has bluetooh but only 2gb ram, Mx9 has 4gb ram for the same price and some users comment about the durability not being so good, unfortunately mi box has 2gb and cost 2x more.
I have a sony tv bravia 42" that i want to watch 4k movies and play shadowverse/autochess only.
Could you help me decide or giving me tips?!
there is a reason the mi tv is 2x more: i.e. better support software, it has chomecast built in and has the required certification. the software is also android tv rather than modified android for phones. sometimes the mx and tx do not have the necessary drm to watch netflix and prime video
if you dont care about prime video and netflix and you are just playing files from the usb/plex then just get whatever is the cheapest as any recent device would be able to decode
there is a youtube channel called chigz tech review that anaylises the boxes. watch his video about the boxes and his charts:
