I personally love my Q9fn especially for how much gaming I do on it. They can get blindingly bright, so maybe do some adjusting depending on your room lighting. As far as PQ goes I still think OLED is top, though I love the QLEDs with full array lighting it just doesn’t get as pitch black as the OLED TVs. Watched quite a few movies on OLED at a friends house, tho I can’t say exactly how they perform on games.
Some of the newer LG OLEDs also have HDMI 2.1 support so you can get 120hz refresh rates. According to Phil Spencer at Xbox they said they will be targeting higher frame rate support with Series X, so that might be a consideration too.
I also agree to check Rtings. They have some awesome breakdowns showing refresh rates for gaming as well as all other aspects of the TV.
