In dilemma choosing between x90j 65' (around RM6.5k-7k) or a80j 55' (around RM 7.5k-8k)...Should I take take a leap of faith to smaller OLED screen size or better off with bigger 65' size TV??

Thanks, decided x90j after I visit shop to compare both. A80J for sure better both myself and my wife feel get "suck into" the scene when we watched 65' OLED and 55 inch just feel bit small and not to mention double the price. x90j aren't lost so much either but provide very bright screen sharp picture quality with reasonable price of 6.3k.
