Saurons Weapon of Choice?

I think this is important. Elendil and Gil-galad were evidently very mighty individuals of their respective races both spiritually and physically. Despite being more powerful, I'm not sure Sauron would try to best them in a contest of weapons but rather a display of sheer force. I picture Sauron emerging in a furious rage literally grappling with his foes - as we've established, Gil-galad was burnt to death by the heat of Sauron's hand. Narsil was not broken by Sauron but rather snapped under Elendil as he fell. Isildur claims to have "dealt the Enemy his death-blow" however, so seemingly it was Isildur who brought the combat to its conclusion. Is there a difference between this death-blow and Isildur using the hilt-shard of Narsil to cut the Ring from Sauron's finger?
