Icecrown would have to be my favorite overall
by era:
Vanilla: The Hintherlands
Burning Crusade: Shadowmoon Valley
Wrath of the Lich King: Icecrown
Cataclysm: Vashj'ir
Mists of Pandaria: Jade Forest

Silverpine takes the cake for me. The scenery, atmosphere, and quests are so well done. It's perfect.
Howling Fjord!
Vash'jir, the most stunning zone in the game, both lore, quests and the zone itself.
Hillsbrad foothills or Storm peaks
Edit: Hillsbrad mainly for nostalgia :P
old Loch'Modan
Surprised nobody mentioned Azshara. I love both incarnations, even if the original barely had any quests.
Nagrand, Shadowmoon Valley, Dragonblight, Storm Peaks, Hyjal, Redridge Mountains, Westfall... (last two are probably nostalgia)
I really like Elwynn forest and Trisfal glades. Both of the zones are extremely good starter zones and I have very specific memories in both of those zones from TBC. Out of the higher level zones I enjoyed Winterspring, Nagrand, Storm Peaks, Uldum, and Townlong Steppes.
pre-Cata Elwynn Forest, pre-Cata Teldrassil (have they even changed it?)
The 2 most magical zones in the game, much due to their music.
They're (short for They are) describes a group of people. "They're/They are a nice bunch of guys." Their indicates that something belongs/is related to a group of people. "Their car was all out of fuel." There refers to a location. "Let's set up camp over there." There is also no such thing as "could/should OF". The correct way is: Could/should'VE, or could/should HAVE.
Holyfury armory
I like all of the safari type zones. Spent more time in Nagrand than any other zone by far.
I like sandwiches
I used to love Stranglethorn pre-cata. I despise virtually all cata zones.
None. The place where I had the most nostalgia (auberdine) was destroyed. None of the zones are exactly pretty compared to more recent games so I can't really say any stand out aesthetically. I suppose the zone I hate least would be Uldum cause it's pretty interesting.
Azeroth before Cata. What Blizzard did to Azeroth during Cata was a crime and one of the biggest reasons I don't sub.
Funnily enough they try to spin it at any given moment to make it seem like it was an upgrade.
But it wasn't. Cata butchered the great world they created.
jade forest kinda blew me away
