LG 70UH6350 or Samsung UN65KS800DFXZA

I feel like Samsung is a better brand but the LG tv is larger. They both have the same resolution and refresh rate but im not sure about response time and input lag if I were to play any games on them which are my main concerns.

I cant seem to decide on one to buy and I need some help >.<

What would you choose and why?
Thank you for reading.

I've got a Samsung UN60EH6003F I've had since 2011 and its still doing fine, I've just been wanting to upgrade to 4k for awhile now. Do you guys know of any sites that compare response times or input lag for gaming on TVs? I tried to play Rockband on a Vizio and there was considerable delay between pressing the buttons and seeing the effects on screen. Im trying to avoid getting a TV with that issuse.
