Samsung has launched the online only AU70/AU60 in similar price ranges which are basically AU7000 with and without multiple voice assistant support. You can look at those than these Philips models in budget range for peace of mind. Would have preferred them to launch an online only model for AU9000/8000 but the creative minds at Samsung India product team have played their game to milk the Indian budget tv buyers by providing the lowest on their global series in two confusing variants here.
I personally would stay away from Samsung. I have a cousin who worked there and he told me many unethical business tricks of theirs during after sales service. I would even trust a Phillips which is like a dying brand. Still they don't manufacture stuff that will bust as soon as the warranty expires.
