imo the choice can only be made by you answering this one question:
Are you getting into it because you just want to run them,
Or are you just as into tinkering with it as you are running it?

If you just wanna run them then go electric,
If you enjoy breaking things down and rebuilding them then go nitro
(electric requires breaking down & rebuilding to, Just not as much)

But thats just my opinion,
Either way your gonna have fun
