OLED v QLED is fairly easy to decide.
If you watch a lot of sports or TV shows that might have logos in the same place for extended periods, then QLED is the better choice. OLED suffers from burn-in over time. I use mine as a PC monitor and my favourites bar is partially burned in now and visible on all lighter scenes.
OLED is amazing for films and good TV series. Especially if you have access to that content in HDR10+ or Dolby Vision.
