i believe ppl are not giving pain enough props in strength. I think he is seriously underrated and is amazingly powerful. Pain is one of the strongest in this manga and i say the strongest in akatsuki... i havent seen madara yet but im going out on a limb and saying he is stronger than him for now.
pain has one of the most devastaing jutsu's and has tons of chakra with the most powerful dojutsu in the ninja world.
pain is the man!
