Oppo's still much overpriced for it's capabilities. Some are satisfied with the PQ (good for them, and nothing wrong with that) and some can strictly tell, that it's over saturated and over sharpened in most cases. Tho' HiMedai's PQ might also not be 100% perfect in synthetic picture tests, but it's considered as one of the best (if not the best) PQ that any Android based player has to offer at the moment.
Yea, Oppo's also lacks the online TV streaming capability, but what I've really meant is the missing network share access and playback. Only with the pricey CFW will it do that. I'm kinda through that uncomfortable session when I've copied the videos every time to a pendrive and ran around with it between my TV and my Computer.
What Oppo's better at: -maybe- in SD, HD and 1080p upscaling (still you will loose some on the side of the general PQ deficiencies and unnaturality). And -at most definitely- the audio playback sound quality on the analogue outputs.
And... That's it.
