I have and like both. I'm a beginner and find myself doing most of my practice on my acoustic because I believe it builds my finger strength faster.

I love the sound of the electric guitar and like some posters have said there are some sounds you can only get with an electric. Sometimes however, it can get a little overwhelming because the electric is all about getting a specific tone with amps and processors and being a beginner I don't want the extra learning curve to interfere with the time I have just to practice the basics.
