i love the full and natural sound of an acoustic, but i learned on an electric and i like how much easier it is to play
i think id say electric. i love both, and have been playing a lot of acoustic, but picked up my electric the other day and forgot how much more license you get. i think its more versatile over all, although theres nothing better than taking the acoustic with you and playing anywhere.
I have to say, I honestly can't choose. I love the bluesy rock 'n' roll sound an electric can produce, and the warm, soft tone of an acoustic. They're both amazing and are fit for different songs. I guess I personally prefer to play electric though. Although around a campfire or sitting on the bonnet of a car, that just wouldn't be right.
