I don’t know the difference but still feel the answer is clearly sorcerer.
That was fun, but I don’t want to keep all the fun for myself. Someone else can ask the questions next week. 
At least in DnD a wizard is someone who studies to learn magic but the sorcerer innately is able to cast spells. So the wizard over time will know more spells but the sorcerer is able to cast a limited set of spells capped only by their what their level allows. Sorcerer's are thought to be able to innately cast spells because they have some dragon ancestors.
Having said all that I'd go sorcerer
Interesting, thanks… that actually changes my answer plus I learned something!
Mage.
Warlock
And the related question: wizzard or sourcerer?
Sorcerer. Or maybe a summoner.
Sorcerer if it lets me drop Blaze in place of Dao and Apollo.
(Internet cookie to anyone who gets the reference.)
Based on DnD 4th Edition, Sorcerer. I'm actually playing one in an ongoing forum-based game right now and she's super-fun (though this isn't entirely down to her class...that just helps) :D. Random crazy magic for the fun!
I'm going to go with wizard. My powers change completely dependent on which setting I feel like using.
Death or Cake?
Cake!
Death… no wait I mean Cake.
Cake. Unless it's a lie.
Death by cake?
I'll have the chicken.
Ahh, that's something I haven't watched for a while.
Cake, please!
#5 Wizard, especially since I'm now immortal and have time to gather spells and components from my flying sky-castle.
#6 Since I'd fill my castle with servants, I'd probably go positive. A happy workforce is a hard-working workforce.
#7 I believe I special ordered the fish.
New question:
Light or Dark side of the force?
