Of course that would depend on the player, a casual player who mostly focuses on casual content would see FF14 as superior, including myself who often does most of the content an mmorpg has to offer and also enjoys doing high end content casually, meanwhile if you are a WoW player who only cares about high end content and you are the type that goes "Show me your arena/m+/raid achievements or your opinion is irrelevant" because their entire self worth is based on video game achievements of course these people will see WoW as superior since it mostly focuses on that and even includes time limited/exclusive content to keep these people feeling special and above the "inferior casuals".
Hell people who are new to WoW ask for mage tower appearances to come back and a huge portion of the community starts raging because that would rob them of that feeling of being "special" and tell people to just never unsub from WoW and that "they should have been playing X bad expac" even if they are literally NEW PLAYERS, probs why they dont stay for long. (They try speak of challenge not admitting your can roflstomp all those time limited content rewards by gear from next patch)
WoW is basing itself on very manipulative and unhealthy design, I dont believe it is on purpose, I believe the devs share a mentality with certain high end players which leads to this, and many people who lack self esteem can very easily get addicted and be unable to leave because the moment they leave they have nothing to feel good about themselves because WoW wasnt a video game for them, it was their source of self worth, that is why you see people hate WoW yet keep playing.
On the other hand FF14 is a video game first and foremost that is made to be fun and to be casually enjoyed, not have your ego depend on it which I find so much more refreshing.
