Hm. Both good...but I think in terms of danger, I'll go for Jaws vs Bond; the compairons between Kiel and Moore is brilliant, in size and power. Bond being thrown around like a ragdoll, and that huge hand over his neck is something you don't see in action films anymore in a stand-out villain like Jaws!
But I always love Bond using a deck of cards to distract a bad guy like he does in 'Live And Let Die'...! 
Bond's best knife throw...
Killing Grischka after being pinned to a door in 'Octopussy'
OR
Killing Silva after nearly drowning in 'Skyfall'
