I've always loved seeing recursive functions I wrote in the past. The amount of power and elegance that can come from a good recursive function is my favorite.
For me it's the opposite, I'm truly proud of those times where the obvious recursive solution is avoided and I manage to solve it with a "while(..){}". I'd be like "LOOK I DIDN'T TOUCH THE STACK ONCE". I'm raised on microcontrollers though.
