Same here, I've been comparing specs, reading reviews researching for the last month, actually last few months. For me, the LG 65 C3 or Sony 65 A80L. 300 more for the Sony.
"The only edge the Sony has is in its processing capabilities; typical of Sony, it's class-leading when upscaling low-resolution or smoothing low-quality content.".
I gleaned this from the site "RTINGS.com.
HDR Native Gradient
LG C3, 7.8
Sony A80L, 8.3
But at my age 66 how much would I be able to see any difference between the two. LG does get Brighter especially in HDR for movies, Sony has the better over-all Processing for HDR, which is what I'm shooting for.
Now of course Sony's flagship A95L Stomps anything on the market as of now, but a 65" will run me $3500.
