Out of all 4, only Hemsworth and Amell have some form of martial arts training. Amell trained in parkour to get ready for his Arrow role and Hemsworth (if we're to believe him) has trained on and off in boxing since his youth.
Yeah, I'll take the Chris team. They have the biggest fighter on their side plus the only one who had actual fight training. Plus he grew up in the Outback with 2 other brothers.
Not to mention that the 2 Chris's have been filming together for quite a few movies now, they should have far better teamwork than the DC team.
