I'd say Fallout 2 is pretty much on the same level as New Vegas, and is almost able to capture the atmopshere of Fallout 1.
Huuumm......Not so much to the sky, nor so much to the sea IMHO. Vault City, Frisco, Reno, Broken Hills, Navarro. They do not remind me at all F1, except for the same 10 npcs haha. Take NCR for example, with all that fancy force fields, a clinic specializing in cyber technology and a police force with jaunty uniforms.
NV is heavily criticized for being very civilized, very advanced, but I think Fallout 2 is that way.
