Paging putra to give further input about his Tanix TX6. Few weeks back, he mentioned it’s working well for his streaming and no gaming needs. Here’s my take on the hardware (sight unseen).. Personally I prefer AMLogic SoCs over the Allwinner H6 SoC. But it’s no slouch either for normal tasks, partly due to its 4GB RAM & decent FW.. IIRC, it’s running Android 7? And Google Widevine L3. The latter not being L1 plays an important role if you are seeking Netflix 1080P. As is, expect the typical max 540p res. As for the Android 7? I’d take a stable & bug free lower version rather than a buggy Android 10.

What are your requirements though? Perhaps if willing to seek others, Take a look at my sig for a few other battle tested options.

Get a Fire Stick 4K. It have all those things you wanted, including Atmos and it's cheap.
