For me, the Aedra vs Daedra debate always goes like this:
Me: If I choose to worship you, will you ever ask me to kill someone who isn't completely evil?
Aedra: No. Never.
Vaermina, Peryite & Nocturnal: No. He stopped obeying me so the guy I want you to kill is evil because I said so.
Hermaeus Mora: No, I'll just wait for you to come back with the blood elixirs or persuade the dude to give up the info then do my killing personally.
Boethiah: No if you can find an evil person who trusts you and considers you a friend.
Hircine: I think good and evil are irrelevant when hunting.
Namira: I won't ask you to kill someone but if you want me to talk to you, you'll have to kill and then eat someone.
Mephala: Only if you want to use my Ebony Blade.
Molag Bal: Yes, right after I force you to murder someone else.
Me: If I choose to worship you, will you give me weapons and armour which are more powerful than something I could smith and enchant myself or effects which could be replicated with a spell?
Aedra: We won't give you anything, but if you find our amulets in the world we'll give them blessings which are outstripped by something you could buy in a shop or find in a chest.
Daedra: That depends on how much you grind smithing and enchanting and what perks you have.
Me: Will you ever put me through humiliating or awkward situations just to amuse yourself?
Aedra: No. Never.
Shegorath: Hell yes.
Peryite: Do you find being vomited on humiliating or awkward?
All other Daedric Princes: We will put you through humiliating and awkward situations for our own benefit as well as amusement.
Me: Will you ever drag me a million miles into the air to boss me around?
Aedra: No. Never.
Meridia: Yes.
Shegorath: Hey, what a great idea!
Me: Do you have a history of killing your worshippers?
Aedra: No. Never.
Molag Bal & Boethiah: Yes.
Hircine, Nocturnal, Malacath, Hermaeus Mora: Only when they start pissing me off or abusing my gifts.
Clavicus Vile: No, I'm just pleased when you kill them all.
Me: What sort of afterlife can you offer me?
Aedra: Sovngarde.
Hircine: Hunting grounds.
Nocturnal: Servitude in my temple then becoming part of the mystic force which aids living thieves.
Hermaeus Mora: Wandering around a place made out of books with tentacles in black ponds.
All other Daedric Princes: Not talking, but if Molag Bal doesn't offer eternal damnation I'll take an arrow to the knee.
Me: Can you cure me when I get sick:
Aedra: Yes.
Daedra: No.
Me: I will you ever kill anyone I like?
Aedra: No. Never.
Hermaeus Mora: Oh, you liked that old Skald you persuaded to give up his secrets then.
Molag Bal: Stop being a drama queen. You knew Tyrannus all of five minutes.
Me: I'm worshiping the Aedra. As well as being a lot safer than the daedra, I also have an appreciation for their hands off and silent approach. Mostly when the Daedra get in touch, its because they want to order you around and/or be a horrible person.
