Sure, electric is a blast, but acoustics are a lot more useful overall. Playing electric is like playing sax, flute, mandolin, fiddle, blues harp, trombone, or banjo: It just usually doesn't achieve escape velocity without a band behind it. A folk guitar is like a piano or an accordion: Fits in fine with a band, but the band is optional. Plus, acoustic guitar is the acid test for song writing. Steve Earle said it best: If you can't play it on a six-string flattop, you don't have a song. So if I had to choose, it'd be an acoustic, no contest.
