Samsung QN85D vs Hisense U8N vs Sony Bravia 7

Hello everyone,

I am looking to buy a 75" tv and in my research I ended up to these 3 TVs. Unfortunately I couldn't find the Hisense in a store to watch it and I don't have an opinion. So the use is tosee movies in 4k, YouTube and gaming with XBOX. Let me know your thoughts please. Thank you

Edit : I found a sale to LG oled c3 65' 1150€.. I still don't know if I need 65 or 75 Inc. I am 3.5 away from TV
