I never nitro. Just started this rc thing.
I'm liking the brushless power. Charge and go.
Weather doesn't bother it to much. Only thing I've found is water and dirt shorten wheel bearing life. I've run mine pretty good already. It's tough - and easy to maintain.
I vote brushless.
I'm an old motor head to but I don't want to wrench or tune. But I know I'd love it if I had the time.
