Help deciding between Paladin & Warrior

Anxiously awaiting the release on 4th November and can't make the decision on which one to roll as a main. Not all that interested in alting as I primarily like to gear out one character as much as possible and invest time on it. Both seem super fun, mainly looking to tank & off-spec as a DPS. At this point, both seem equally fun so I suppose the decision will come down to which do you think will be more valuable / convenient in end-game content, whether it's dungeons, raids or pvp.

Rolling on Alliance PVP if that matters. Feel free to speculate, come up with your own theories why you'd pick one over the other. No beta access so won't be able to test out the kits up to lvl 30.
