^depende kung saan mo ilalagay ung TV, if in a darkened room with small windows, go for the OLED. Pero if sa sala with several windows tapos minsan bukas pa ang pinto, go for the LED TVs. In a brightly-lit room, LED TVs with backlight could produce a lot more nits than the OLED and would looked "better" in terms of PQ.
However sa gabi, dun naman lalamang si OLED, unless malakas ilaw ng sala mo.
