Nitro, NItro, NITRO! Once you get them tuned right there's nothing like it... When you see a Traxxas Rustler w/ a Pro .15 on it get trashed into a curb at WOT at about 30 mph and smashed up, then you rebuild the ENTIRE TRUCK (yeah, that was fun lol)... THEN swap a 2.5 onto it and see that thing hit its first 50 mph pass and hear it go "WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHH HHHHHHHHHHHHHHHHHHHHHHH!" .... nothing like it! Electrics dont sound like that, I have two Nitro and 2 Electrics... Electrics are easier to operate as far as no tuning and such, but Nitro is so much cooler in the end!
