How strong/powerful would composite Tarzan be?

[KJ Stewart]

For some reason, this Saturday evening I find myself watching the 1984 British adaptation of Tarzan ("Greystoke: The Legend of Tarzan, Lord of the Apes").

Got me wondering how strong and/or powerful (assuming some versions might have a power I'm unaware of) a composite Tarzan would be. Include in the composite things like speed, agility, durability, senses etc.

Anyone familiar with enough versions to give a decent answer?

I am personally familiar only with a couple of the old novels and assorted movie adaptations, but he might well have some odd stuff by way of Farmer's Wold Newton universe.
