Good Honors Colleges and Programs for Average Excellent Kids

I would appreciate some discussion on what are the best and very good honors programs for an average excellent student. I have been looking and see a lot of programs that just offer the nicer dorms and priority registration, but not much else of substance other than a few smaller classes in classes that may not be relevant. What programs are out there that make a material difference for the students who participate? (Bonus points for data that shows that outcomes for Honors students are measurably better than non-Honors students with similar stats for med school/grad school/otherwise).
