It really depends on just how much you want to work on them. If you want clean and very easy to maintain, stick with Electric. But, if you want the max amount of fun, the best smell and sound in the world, and don't mind tuning on them, then go Nitro.
If I had to choose, I would always choose Nitro. There is just no getting over that smell and the feel of the power. I love tuning on them, and know how they are supposed to run though. For a novice, electric all the way.
