Fallout NV had much better writing. Story wise the wooden facial animations in Oblivion and Fallout 3/NV really detracted from the experience for me. Not that any of those stories were good to begin with except for NV with its plethora of choices and dilemmas to progress the story. It really felt like a transition from the chaos of the Wastes to a more 'orderly' society dictated by factions of which none were particularly sympathetic.
Fallout 3 however, while lacking in story, I found more interesting to explore. It felt much darker as well, with an often creepy vibe that reminded me of Silent Hill. I just loved exploring the Capital Wasteland. I never played any Fallout game before though so I just enjoyed it on its own merit.
So in all I found the main story of NV much more engaging but the world of FO3 more interesting to explore. Both are great games though but I think FO3 has my slight preference.
