For me, it's without a doubt Dragon Quest XI. It's one of my games of the generation and represents exactly what I want out of an 8th gen jrpg. I really wish SE would stop trying to reinvent the wheel and use DQXIs template for a final fantasy game, but we all want things :/ I'm not sure how i'd rank the remaining 3 however. I like all of them to a degree, but they all have flaws which I feel hold them back in different ways.
