Best TV from Costco under $800?

Which TV is better for gaming, movies and sports? Costco currently has the following with the warranty included:

TCL Q77K 75 inches for $500

TCL QM6K Pro 75 inches for $750

LG 77 OLED B3 (Currently out of stock but hoping it will be back soon) for $800

Hisense U75 75 inches for $800

Any recommendations or experience with any of those TVs?
