kinda depends how far back you're willing to go graphics wise. I'd vote for FF12 Zodiac Age. I enjoyed FF7 Remake but I'm not sure of the experience if you don't have any nostalgia attached to the original version. FF8 remaster is good too but the original was released in 1998 so not exactly graphically impressive. FF15 is good too but the gameplay is pretty different from previous versions.
