I still think it's Oblivion. Sure, it's pretty clunky in some of the interfaces and whatnot, but that first moment when emerging from the prison sewers is still unparalleled in my opinion. The vastness and freedom is completely overwhelming at first, which is why some people give up on the game before they even get started.
I haven't played GTA: San Andreas, but opinions and reviews lead me to believe that it may rival Oblivion.
