Natsu is immune to fire, Ace is immune to fire and can become inmune to bludgeoning, Natsu's only attacks. However, Natsu eats fire whilst Ace can turn into fire. Ace is naturally stronger and faster, but it's only a matter of time before Natsu eats him. If Ace plays the dodging game correctly, however, he should win.

May, but I prefer Natsu VS Luffy.
