I have two variants of the biggest armor.
#1
I was thinking that based on the image, it would increase his strength by another factor of five. That being said, he would be able to dash very fast, but that also makes him somewhat clumsy.
It's hard to actually run in the armor. He would at best, run at 30 mph. It allows him to lift 440 metric tons (about 485 US tons) and weighs 5,000 pounds.
#2
No bonuses other than higher defence, stronger shields, and possibly a better reactor. It's not really a whole new suit, it's just permutations that John can add if he wants.
He still has the normal undersuit, so his reflexes, strength, and speed are the same. That being said, John loses mobility and is not as agile as before, making him more susceptible to getting hit.
