I loved Oblivion and I'm loving this. I do like the setting of Oblivion since I'm a fan of fantasy and I like the guilds etc. I do enjoy the shooting aspect of Fallout 3 and the VATS is top notch, well esp since without it, aiming is a bitch. If Oblivion had the improvements done for Fallout 3 then I would probably like Oblivion more. Improvements include the exp system, and a lot of little things I can't recall off the top of my head.. like I dunno the key loop, ammo not affecting weight. etc etc, FO3 is amazing though.
