Hi guys, need some recommendations which android box should i buy, im interested in mi box s since it is a certified netflix, meaning i can play 4k netflix. My first android box was tx6s 4gb ram+64gb, That time i thought highest amount of ram and storage is the best android box and i dont know anything about netflix certified device, and end up only able to watch netflix at 480p. I also cant download app from playstore properly. Only after that i understand this kind of android box isnt certified, which limits streaming quality of some apps, I hate it and sold it.

My usage will be able to watch netflix,youtube,hbogo,disney+Hotstar and myb most ott apps without any limitations. also can i install astro go too? i dont need any preinstalled free movie apps. Should i buy mi box s or as some others i saw recommending mecool km2, but the price difference about 100, mi box around 220-250, mecool above 300. Im not really familiar with mecool brand,afraid it will be just another non certified android box.

Thank you
