Johnny Galecki while not particularly a stand out in the role of Rusty in Christmas Vacation has probably had the most commercial success post “Vacation”.

Anthony Michael Hall, the original Rusty, had a pretty successful career throughout the 80s-90s. Juliette Lewis, Audrey Griswold in "Christmas Vacation" would earn an Oscar nomination two years later for "Cape Fear" and enjoy a great deal of success throughout the 1990s.

Another Griswold who went on to greater fame was Cousin Eddie's daughter, Cousin Vicki from the first movie, played by Jane Krakowski, who would go on to receive multiple Emmy nominations for her role on 30 Rock.

Jane Krakowski...i’ve had a crush on her since we were both kids.

True. Anthony Michael Hall and Juliett Lewis and Jane Krakowski have kept working over they years and have had successful careers.

I guess I'm thinking about how much the cast from the BBT makes and how huge a hit it is and in syndication. Heck when I went to the UK last year and turned on the TV in my hotel room, what was on? The Big Bang Theory.
