I agree, though it might be best to pick a city that houses guilds for professions you plan to focus on. Ul'dah is a nice, central location, though personally I don't like the landscape much. The city set up is very nice though I think most would agree. Gridania is probably the least populated, mostly I think due to the corridor style zone layouts. Limsa Lominsa is a good place and probably the highest populated. The city set up is pretty decent, but most of all, it's where you'll find the highest drop of wind and lightning crystals, the two kinds every crafter is always short on. If you're a crafter, you're going to spend a chunk of your time here anyway farming crystals, and if you're a hack and slasher, it's a great place to make cash off of crafters, and occasionally pick up a nice, expensive item that someone is willing to trade for a big stack of shards (got bronze knuckles this way in beta).
At the end of the day it doesn't really matter, as you'll probably spend time travelling between all three. If your play time is very limited, I would pick the one that has the most guilds for the jobs you're focusing on, because you won't have much time to travel, though conversely, you should have a good amount of anima if you're smart about it, so maybe you can teleport around every couple of days instead.
Myself... I chose Gridania:
-Lancer Guild, and I'm a Lancer Main
-Leatherworker Guild, my main craft
-Good looking scenery and peaceful music (though gets too dark at night with rain)
-Least populated, so less competition for camps
To each their own, in this sense, you can be successful no matter what you choose.
