I would have said Tonberry is a good world to go on but it got kind of shitty around the 3.1/3.2 mark.
From my experience with JP worlds, yes they're much better than NA worlds I just love how organized things are to run smoothly with little to no problems.
I like their "Try your best!" attitude
I like how they know how to do Alliance raids the correct way...which seems to be lost on English speaking worlds.
I think sometimes they can be a little passive aggresive when irritable but rarely ever seen a salty JP player
