Saltwater Crocodile vs Nile Crocodile
Quick answer
In a hypothetical one-on-one, the Saltwater Crocodile would most likely come out on top in a close contest, thanks to its a more favorable balance of size, strength, and weaponry. In reality, animals like these rarely meet, and both would usually avoid a fight.
This is a hypothetical, educational comparison based on typical size, strength, and natural weaponry. In the wild these animals rarely meet, and most encounters end without a fight.

Nile crocs line African rivers and lakes; salties span Southeast Asia to Australia including estuaries and open sea. Both bask and ambush at water edges.
Saltwater crocodiles grow larger (6–7 m) and are more aggressive; Nile crocodiles are formidable ambush predators of African rivers. Both kill large mammals, but 'salties' dominate in size and marine ranging.
