I've always thought of FFXIV's character models as one of it's strong points honestly. After staring at WoW's cartoonish models for 15 years, this feels like a major upgrade, but I understand the more realistic approach isn't for everyone. The gear/glamour/transmogs in FFXIV are also vastly superior in my opinion.

In terms of game environments/terrains, though, WoW comes out of top in my opinion. Granted FFXIV does have some beautiful sights of its own but once you get closer, it all starts to look empty and pixelated.

Still, FFXIV wins in terms of overall visuals in my opinion.
