I agree that Super Street is less technical (provided that you even consider them technical to begin with, in which I do not) but the writing is horrid. Their editorial style is like a 14 year old girl.

Example:

Super Street: Oh, my fuckin' god this part is soooooooooooooooooo beautiful!

Sport Compact Car: This <insert aftermarket part there> is gorgeous to look at.

I am trying to say that Super Street is a bit childish in a sense.
