I never owned OLED TV but came across LG OLED Evo C4 on display at JB-Hifi. It was completely amazed by the quality.
Is it worth spending extra money to purchase this TV? Hisense U8NAU is literally half a price and some people say that probably U8NAU is good trade-off but also not a big fan of Vidaa.
As a CS (C1 Frame, C2 Panel) owner, I'm very happy with my purchase. Bought during a Black Friday sale in 2022 for a massive discount ($2200 for 65").
Can't recommend the range enough and would recommend waiting for BF this year to get a good deal. Would likely bring it to a 50% premium to the Hisense, which is well worth it at that point.
With any of these TV's, the stock sound is rubbish, so invest in audio at the same time.
