Fallout 2's stuff is definitely less prevalent, but when it appears it is generally a lot more obnoxious. Dr. Who references are more immersion breaking than shitty Thunderdome references, at least for me. Ultimately the scales are in Fo2's favor because as you say the stuff is more out of the way, and the rest of the game is almost universally better written from both a narrative perspective, an RPG perspective, and a lore perspective.
