Performance-wise, both can be made ridiculously fast, but electric has superior acceleration.
There is no 'same' truck, you're really comparing apples and oranges, it depends on engine / motor size and gears (nitro) or battery (electric) and many other variables. But recently most of the people who still use nitro are not using it so much for the speed or performance, more for 'the noise', 'the smell', or other aesthetic reasons.
