One HUGE factor is Integras get stolen A LOT!!!!!!!!!!!!
I personally liked the lude over the GSR when it was time to buy for the more solid feel the Prelude had. If I like a car I could care less if they are dime or dozen or unique. The Integra has awesome aftermarket support and make some serious power despite the 1.8. The less torque is made up for with the lighter weight so the power/weight issue doesnt' mean too much to me.
