Recommended UHD Player - Xbox or standalone?

[SPIDERone]

Sorry for the question - I'm sure it's been asked. I didn't see anything about it and wanted to get some opinions.

Buying an LG OLED 4K display tomorrow and plan to use it mostly with movies (Blu, 3D, DVD and 4K)

I was planning to get an Xbox one S for the price, but gaming isn't a big concern. It might get minimal usage for games if anything. I'd rather get a higher quality movie experience if there is one.

I see a couple players and I'd like to keep it around the $200-250 price. Streaming options not necessary but if they support 4K playback via
USB or hard drive, that would be awesome. 3D playback is needed though.
