I think FFXIV and WoW both have strengths and weaknesses, so just giving it a shot will help you see if you can handle how FFXIV plays.
To me, things FFXIV has over WoW are
(1) story is more cohesive: Just like in WoW, sometimes you have to just overlook things that make no sense, but the story had a long arc and it was overall done decently well.
Bad part: They have an antagonist they can’t seem to let go of who keeps turning up in the story like a bad penny. My friend and I jokingly call it “the Syvlanas effect” lol.
(2) armor looks great and can be dyed: FFXIV armor doesn’t look painted on and most armor can be dyed so you can create a specific look for your character. Dyes, though, can be super expensive.
Bad part: The way you store glamours is a massive pain the bum. Organizing them well is nigh impossible unless you want to use glamour plates. Also, you can run out of space.
(3) loot is deterministic at max level: When you first reach max level, you can start earning Tomestones that you spend to buy ilvl 580 gear. You could buy every slot except you can only buy one ring. When they added the 4 Savage bosses, they also added crafted gear, so now you can just visit the AH to kit out your character in ilvl 580 gear. (Max ilvl gear is 600, with the weapon being (I think) 605, all earned in Savage raiding.)
Bad part: To maximize getting these Tomestones, you must do the Daily Roulette. That means that your level 90 character can land in a level 16 dungeon with 90% of their job’s buttons grayed out. It feels terrible to play.
(4) there are few chores at max level: Besides Daily Roulette for Tomestones, there’s very little daily upkeep for your character.
Bad part: Honestly, there’s very little to do at max level on your character unless you are part of a Static team that’s progressing in Savage raiding. There’s no challenging dungeons like mythic 0 or mythic+. The small man content is practically fail-proof.
WoW, however, has FFXIV beat in the small man content. You have ever-increasing challenges in mythic+ to aspire to if you so desire, which adds a lot of fun end game content for those with a team of friends for grouping.
I don’t do PvP in either game, so I have no insight regarding that. I also don’t craft in FFXIV so I cannot compare the two games.
There’s other minutia about FFXIV I like, but I’m out of time so no more posting.
TLDR; I’d say give the game a shot and if you can make it into the first expansion, which is Heavensward, the story vastly improves. It’s rough, though, the base game’s story because it is such a slog. Good luck!
