Both actually, I just found it easy to make an unkillable tank in DA2, sitting on 80 % magic resist, dmg resist, armor and defense atm... But I still like it, DA2 has more of an action rpg style with a lot more focus on the interrogation part of the game with other npc's etc. Wehre as Dragon age: Origins had a lot more choises in how you wanted to play, who you wanted to recruit, etc.

There is also the mod called Hentai Mania for Oblivion, which adds a ton of dungeons with rewards and a progression line. Let us not forget the more races mod, like chocolate elves etc. By using these you can get a vast amount of different looking npc's, Companions (through a mod) and pc's.
Oh and oblvion has gooten a lot of praise through the years, I tend to go back and play it for like 3 hours every week, mainly because I have turned every single stone in the the game + my 70+ mods.
