Best LED TV for gaming?

Hi. I’m looking to buy a TV for gaming mainly (not just retro gaming). In the sea of too many options it’s hard to choose. It has to have:

  • 4K 60 Hz
  • 43" (to fit to my space)
  • low input lag and response time
  • good blacks (local dimming)
  • Picture in Picture feature is cool but not mandatory

Please recommend me something and tell me why I should chose it.
