I'm trying to decide between the Philips 55PFT6550 and the Philips 55PUT6400. The PFT is 1080p but with 3 sided Ambilight, and the PUT is 2160p without Ambilight. I don't know much about TV's and would appreciate advice on which of these two you think I should get and why. I will be mostly watching movies and series on it, occasionally playing games on it from my PC. Thank you.
