Nitro really won't give you longer flight times if you get good batteries. But Nitro will give you more even flight, as far as power. A electric plane will get weaker and weaker as the flight goes on. Where a glow plane will stay the same the whole flight.

Unless you only plan on getting a park flyer (maybe ready to fly), an electric plane isn't going to be any simpler than a glow. Actually I think that electrics are more complicated. You have everything a glow plane has (servos reciever, battery,), and then some (speed control, motor wires). The only real advantage as far as simplicity for electric is that you dont' have to deal with the motor not running. But with electric you have to deal with charging batteries and waiting for them to charge.
