I don't get this post. Did I somehow suggest the C9 was inferior?B9 has 2GB ram instead of 3GB on the C9, B9 has lower HDR peak brigthnesss, b9 has worse near black and shadow details due to the weaker chip, b9 gets updates and bugfixes less frequently than the C9 model, b9 has worse upscale.
No doubt B9 is a fantastic piece of kit but C9 is better.
Rtings rate the B9 as the 3rd best TV, meaning it is rated even better than last years best or the year before. So how big is the difference you are actually talking about?

The difference between the B9 and C9 is actually very small. Not worth the extra money imo. If others want to spend all that extra money on small difference, they can be my guest.
