Truth is I liked the B650's Contrasts better, but not it's detail in dark areas as much as the B750.
Also the B650 seemed to have better viewing angles,
but then again it's contrast ratio must have helped play this trick on me.
Despite the seemingly lower contrast ratio & narrower viewing angle, & because of what appeared to me as a gamma & shadow detail advantage alone, I decided I am going with the B750.
(Also I gave up on the 52b750 because I liked the 46 better, it had more power to the picture - at least on the tvs I tried)
But I am lost between the 46C750 & 46B750, I could really use a pros help.
There is no way for me to see it in action, I can only buy without seeing it first, & I must make the decision in 2 days time
