This should have clued you in: "Short answer: yes, but he still favours swords."

Do you really think that Kirito is good at anything else other than swinging swords like a hot blooded idiot?

Kirito's main weapon is a Kagemitsu G4 photon sword and the antagonist has an estoc.

Later on, in the Alicization arc, it is mentioned that someone didn't even bring weapons and used a grapple to get close to his opponents and use their own weapon to kill them.
