Not necessarily, but Jonathan Hickman comes to mind. He generally writes a Thor I imagine hearing. Sort of like the "Earth's Mightiest Heroes" cartoon where it blends some of the Middle English with modern proper English. His Thor speaks quite properly. Aaron's Thor is more "tough guy, cool" type speech that Bendis also did, though he peppers in some classical Thor-speak here and there. So is Fraction's. I don't think a writer has to bring back the thees and thous for the Asgardians, but they sound way too human for my tastes. Sort of diminishes their unique personalities.
