I have looked around for post descussing people opinions on this but havn't found any so im going to start my own... i may be wrong!!
basically i personally think that gilneas looks like a real sort of WoW city, not saying the others are crap but imo they all look too... well fake within the game! i know that they are all representing stuff like IF is the mountain city of the dwarfs etc etc, the obvious stuff... but this time i think blizz have really made a good design. i always thought that SW was the most popular city and to me it was the most real mystical city ingame having that sort of feeling! to me Gilneas looks like something out of lord of the rings, or harry potter, you know those sort of mystical films, and to me wow is in that same category. again this is still my own opinion!
bit of a strange post i guess but it would be nice to see other people's views!
cheers
