Just my 2 cents. If I had to choose between the two, I would take the NGKs without hesitation. I use NGK & Autolite, but if the NGKs are on sale or something, I'll pick them. I've had nothing but bad luck with Champion plugs a few times years ago, (had major fouling issues with them in a couple of my Mopars) & have not used them since. I replaced them with Autolite plugs & the car ran fine. (I only changed the plugs & that's why I don't use Champion's anymore) Never have a problem with the NGK's, matter of fact, I'm putting a set of NGK V Power's in my 01 V-10 Ram soon.
