1. Don't have to wait 30 min in Queue for the dungeon finder because you are DPS, just need to find 4 more and you are ready to go because there isn't holy trinity, everyone must keep tab of their health, defensive cd and looking the enviroment to survive.
2. No subscription, so you are free to play it when you want and can take time away from the game to play new games without wasting your sub play time.
3. The game empathize in exploring, there are hidden challenges, skill points, places that you can find if you decide to.
4. You don't need to fight with other people to complete quest objectives, no kill/item stealing. everyone contribute to complete the quests (events in this case), and everyone receive rewards.
5. Multiple ways to complete quests, you can kill monsters, waters crops, taste beer, etc.
6. Its less gear based and more pay attention and play well.
7. There is Transmogrification so you can combine different design of armos, also the Dye system allow to make a lot of color combinations to personalize your character.
8. The Personal history is a series of events and a special zone in your race capital city where the choices you make in it are reflected in your special zone, its like a single player where you can take paths, take decisions and shape the history of your character.
9. WvWvW, World vs World vs World, Its a PvP zone where you take towers, castles, keeps and supply lines with siege weapons and blood, if PvP is your thing and don't want to lvl with PvE you can Lvl to 80 with WvW.
10. sPvP its easy to jump in, just create a lvl1 character, finish the tutorial zone, jump to the mist and you are scaled to lv80 with all the traits (like talents) and skills unlocked. You are provided with PvP gear. Tho the gear in sPvP isn't so important like in WoW arenas/PvP, the sPvP its more skill based, but you get gear rewards to change your look.

12. There are dynamic events that change the world, some town attacked by bad guys that if you fail to defend, they take control and you need to retake to free it for example, but also there are bigger events where you start doing some simple stuff and it evolves in fighting a giant shadow swamp boss.
13. The scale of the bosses are impressive:

There is more but that is what i have in top of my head. The game is good and its a breath of fresh air after WoW and their clones.
