If you have the money, getting any other TV other than OLED would be a waste of money. If you really want LCD, then go for the Sony Z9D, best LCD ever made.
Personally I'd wait, my 2010 Plasma still works, HDMI 2.1 with VRR will soon be added to 2018 sets and HFR (120fps) is the next frontier for TVs. Then TVs will have all the dream features: OLED, 4K, HDR, VRR and HFR.
