Do your home work, OLED does suffer image retention. If you are not someone who plants on a favorite channel (with a logo) it may not be a problem, but it can happen and there are disappointment stories on Youtube.
In general I would not argue OLED is the way to go, but there is one exception, the Sony Z9Ds. Just as it isn't fair to compare a $500 guitar to a $5000 guitar, it isn't fair to compare a low end LED to a pricey OLED.
Currently Sony has priced it's 65" OLED (A1E) and top end Bravia LED (Z9D) at the same price, because they are comparable, even to Sony. The OLED does true black and has better off axis viewing, the Z9D does HDR (color) better and is the brightest television on the market, both are amazing.
If you're shopping OLED (65" or higher), do an A/B with a Z9D (which start at 65"), let your eyes decide. The LG/Sony OLEDs are wonderful, but a 75" Z9D followed me home............
Edit - 5 stars on the OPPO 203, you really can see the visual improvement over lesser players.
