I know the last attack from Pein was really destructive in comparison of everything we've seen so far, but like I said in my post, Pein and Madara are the strongest you'll get in the naruto universe so they have to represent pure power. Plus, we were all waiting to see what THE MOST POWERFUL EYE TECHNIC were able to do (most powerful mean there wont be anything stronger after this) If you want to consider this has an ameliorated version of dragon ball you can, like someone who wanted to help you said ; it's your opinion. Just remember that unlike dragon ball, naruto's character have a limit, and they're about to reach it.
