Of all the 4 tanks right now, how would you stack them against each other?

In terms of playstyle

GNB
PLD
WAR
DRK

In 2.0 i main PLD because rage of halone was so cool at that time i decided to drop SCH/MNK to tank for the first time in a MMO. Then 3.0 hit and i've been a DRK/PLD so total i have about 6 years worth of tanking experience. Tanks should and always be Emnity generation and defensive ability first before DPS. So by going from the definition

PLD is still supreme in MT or ST/OT role. Warrior is still warrior, big numbers coming from fell cleave what not to like?. GNB i am having tons of fun with this new tank as it requires the player to be constantly on his/her toes hitting every button you possibly can either to DPS or mitigate. This is the kind of playstyle i wanted in DRK but oh well.

DRK i have leveled to 80 and it's soooo boring to me now it's like such a braindead job. For DRK if i get to pick i rather go back to 4.X DRK playstyle instead. I rather be spamming dark arts than this boring playstyle.

From what i have seen so far i would go something like that:

PAL
WAR
GNB
DRK

I have only played WAR so far, started leveling PAL, feels nice, dmg should be amazing at 80. Gunbreaker and Darkknights seems weaker to me, mostly because of there strange cooldowns.
