I am a bit biased on this b/c I play both FFXI and EQII =) to me EQII requires less of my time and is much much easier to gain lvl's in than FFXI. You are right however on the fact that FFXI's Economy is ruined. I blame that on its Popularity and skill rating (hard to get) items that require either money or 200+ people sometimes to get.
FFXI: To me is more party based, there are NO jobs that are not need (EXCEPT DRG mwuahahahhahaha) There are also NO gimp jobs. FFXI is more adaptable as in you can play every job it has to offer on on chr, so you dont even have to start over everytime you want to try a new job, and you become more adaptable. FFXI also requires more skill in party setups, with complex battle features such as skill chains, mana bursts and knowing when to cast what (but that is also in most MMO's)
EQII: I have noticed that it is more enjoyable leaving you with an option to play at a slow pace where you dont have to be on every single day to play the game nicely and not fall behind, I love the graphics a lot better than any I have ever seen in FFXI (of course I play on max settings I have an awesome laptop.... and yes I say laptop! :P) I also love the different class choices, how you can customize your chr more, and even have the option of changing its look when you get bored with it.
WoW: omg...... this game sucks.. w ok? :P (w = lol jpn style)
Difficulty wise, FFXI > EQII, less stressful, better graphics, and more enjoyable at times EQII > FFXI.
