Smaug vs The Dragonborn

I hope the moderators will allow this because there have been several fan made films about The Dragonborn.

Who wins this epic fight? The ultimate dragon slayer or the legendary LoTR dragon? Both are at their prime.

You could have a mod throw this is "Foreign Cinema".

If the Dragonborn can kill multiple dragons on his way to transporting to a Valhalla type realm and take down the ultimate world-ending dragon in Alduin, he should be able to take down Smaug.
