I had the exact same choice, I took the XE93.
The biggest factor for me is that I find ANY possibility of screen burn unacceptable. Sure it will not happen to everyone and I think I'm safe in saying it will not happen to most owners, however having to babysit a £1500 purchase is just not right. There is the possibility there and with a manufacturer unwilling to provide any kind of back-up should this occur, I believe that OLED simply isn't ready for mass consumption yet.
So, image quality will not be as good on the XE93. Saying that I've been nothing but amazed with the TV. Everything I've thrown at it looks amazing. Excellent HDR performance, Netflix and the PS4 Pro look stunning with the right inputs.
The XE93 suffers at the bottom end, it's an LCD so the blacks on the OLED will look darker. However at the other end, the LCD looks brighter. The backlight is nice and bright on the XE93 and in my opinion at the bright end, the Sony looks better.
Only you can decide if the possibility of screen burn is acceptable to you - are you risk adverse? When I spend £1500 on a TV I'll be keeping it for 5-6 years, having screen burn after 2-3 years would not be acceptable.
I decided that this would be my final swansong to LCD. I would get a TV that looks stunning, has amazing HDR performance and no chance of burn in. Then, in 5-6 years time I'll look at either a fully mature OLED technology or MicroLED.
