This is INCREDIBLY difficult list to make since the man has so many classics under his belt, but imo... here's his top 5. And I know my list might be a bit controversial, because Schindler's List comes just shy of making it.
1. Raiders of the Lost Ark
2. Jaws
3. Saving Private Ryan
4. Jurassic Park
5. Close Encounters of the Third Kind
Honorable Mentions: Schindler's List, E.T., Duel, The Color Purple, Tie between Catch Me if You Can and Minority Report
