What is the difference between a Honda civic and Honda Prelude? What's better for upgrading for performance?

I love both the Honda Prelude and Civic hb and plan on getting one of the two soon. I want to have a car that has a lot of options as far as upgrading the performance of the car. Which car would be better for that? I preferably want to stay with Honda, but are there any other cars that are specifically good for what I want that may not be Honda?
