I was long deciding between the LG C2 48 inch vs Samsung QN90B 50 inch. Primary purpose was gaming, Netflix, Movies. My impression was LG OLED looks amazing when cranking brightness to Max (Showroom conditions), whereas Samsung Neo Qled is able to match the same brightness at 40% setting, also colours appeared punchier with the Samsung with better Shadow details.
I ended up going for the Samsung and it's been 1 month and I'm loving the quality. I'm glad I didn't choose the LG OLED because I hate playing safe and under utilising a product. With the Samsung, I have NIL worries over burn in and additionally company warranty is also provided for 10 years against burn in panel damage.
