You can learn guitar on either.. Same note, same scales, same chords. You will most likely get GAS (Guitar Acquisition Syndrome)anyway. While you are learning on your acoustic, you can study up on what type brand/style of guitar you might like to purchase. Try everything you can get your hands on. Of course with electric you need an amp.. That is another thing you may want to study up on..
Have fun on your guitar quest..
