Love my LG C1 OLED. I’d definitely recommend an LG OLED

I would always say OLED, just make sure the one you buy supports VRR and ALLM. Most OLEDs support ALLM (Auto Low Latency Mode) which is great for any game as it minimizes all the TV filters that contribute to input delays or terrible colors that exaggerate contrast/brightness for wow factors. Some of the cheapest OLEDs do not support VRR. VRR is great for games that support it, which allows many games to run higher framerates than originally advertised. Only games and TVs that support VRR will use this feature. It can also help smooth out some of the jittery games that run less than 60FPS. Sometimes 40-50FPS is fine, most of the time 30FPS is just too bad to play. Be sure to check your TV supports 4K120, should mean it supports ALLM and VRR.
