Both have the same amount of magic resistance, but Malphite has no AP without items, whilst Galio has 15 from his passive. Galio starts ahead on terms of magical power.

If Galio uses his shield, he gains a great deal of additional magic resistance, which increases his AP even further. Also, he heals if Malphite hits him.

Malphite deals additional damage in his Ground Slam because of his armor, but I don't think that would be enough, because Galio will deal extra damage in all of his offensive spells because of his extra AP.

Malphite can hit harder with his punches, but that extra damage hits him back in the face if Galio ults.

Malphite could knock Galio up, but since he flies, that's not really a problem.

Malphite's passive only refreshes if he is out of battle, which would be after the duel ends, so he can only enjoy his shield for a brief time at the start of the duel.

I'll go with Galio. He is more resilient (shield that heals, increased magic resistance), and more powerful (his Runic Skin converts this increased magic resistance into increased magical power).
