New TV Purchase

Hello,

I had a Sony XBR-65X850B for over 10 Years and it decided last night it was enough lol. No power.

Was looking at upgrading the TV anyway to a larger one (~75 inch). I have always been a Sony fan and haven't ever owned any other TV brands. Costco (Canada) had a few TVs on sale for boxing day. Two TV's had great reviews:

The exact model of the Samsung I can't seem to find outside of Costco, assuming it may be a specific Costco model (ends in ZC instead of ZA).

Mainly watch movies and sports. Does anyone have any recommendations between these two or another the would recommend.

Thanks.
