I've missed a ton of them, but based on VI, probably not IV or V. I'll go with XIII, mainly because it has great lore and a good story that are supported by great, diverse visuals. I haven't played XVI yet, but XV has a pretty boring world and visual style, and the same goes for XII. I can't speak for XI or XIV, but as far as I've seen, XIII is the last time the series had such a great world, lore, and visuals (I really appreciate the colourful, diverse look of X and XIII). XIII is definitely a flawed game, but I don't think it gets enough credit for the things it did right, and even the criticized parts aren't as bad as people tend to claim (although gameplay is really boring for the first 20-30 hours - that's just inexcusable).
