The Pro's : The symbiotic suit is very versatile being able to adapt to each new host and take something from them , it usually gives it's wearers an amp in strength (it can ether double your base strength or double it adding on the same strength the previous wearer had) , and has various shape shifting abilities.
The Con's : The suit is a living being , as such your going to have the suit nagging you to do things which will feed it (it feeds off adrenalin) , it also can leave you at will unless your permanently bonded to it. Finally the suits two weaknesses are readily available.
Mjolnir on the other hand has quite a few pro's and very few cons.
Pro's : The hammer is near indestructible and as such it hurts like hell when impacting against your opponents skull. You usually become an incarnate of Thor when wielding the hammer , it also bestows weather controlling abilities , various amounts of energy manipulation and you can also remove souls and slow time.
okay all I'm saying is if the suit get on hulk like in what if 32... thors hammer= garbage..
but other than that, this says it all:
