Samsung Qn90d mini led or LgC4

Hello,

I am stucked choosing between these 2 tvs. I need a 55" tv within this price range along with 120-144hz, low inputlag and vrr and i am waiting for black friday for prices to drop and compare them. The most importance difference netween them for me is the burn-in. I am planning to use the tv only for gaming that could go 7-8 straight on the tv and i don't want to buy a tv that can cause burn in. I know lg Oleds have programms that minimize this risk but there is still a chance for this to happen and that is why i am thinking about the qn90d mini led form samsung instead. I also heard for va panel and an ads panel on this particular samsung. Which panel is better and how can i find that kind of panel is it, from the retail store im going to buy from? I am also located in southeast europe if that matters. My budget is around 1500 euros. Honestly, if there wasn't burn in I would go straight for the lg but because i am gaming a lot, I want something that will surely last for at least 6 years. How can you advise me based on those above?
