I've always had an electric dryer but when I moved to IA the gas hookups were there so that's what I went with. I also had a gas water heater but due to improper installation of my chimney liner I had to switch to an electric water heater or pay big bucks for having a high cost upgraded water heater and vented out the side of the house. I see my power bill soar due to this. Wish I had my gas water heater back.
I find the gas dryer dries faster for me though I never really timed either one to know for sure.
