I love my human noble rogue Aedan (yeah I kept the default name because I thought it was cool). He married Alistair as well.
I actually liked the magi origin. It was really cool to see all the lore from the perspective of the Circle Tower itself and how the mages are treated. I actually played Dragon Age 2 first, so to get Anders' and the Hawkes' perspectives on the mage-templar conflict and then go back to Ferelden was a trip.
Dalish elf origin was alright. I thought it was a little boring to be honest. I think the Dalish are one of the least fleshed-out factions/races in the DA universe, but I did think the Warden got a good insight into their culture during the werewolf campaign later in the game.
Dwarven noble was hilarious, one of the most well-done ones I think. Haven't done dwarven commoner or city elf yet.
I feel the closest to my human noble rogue. He's my canon Warden.
