Honestly, this is a close match. I just think Team 2 has too much versatility. Team Cap is pretty much brawn and bullets. Team Arrow has speed, sonic attacks, fire attacks, Ollie has various trick arrows, in most recent showings uses swords, and other gadgets, and has improved his skills to the point where he can stomp Nissa and fight evenly with Ra's. So while he won't beat either Cap or Bucky, he has enough feats of hanging with superpowered people and peak humans, that he can at least keep them busy. Remember, in character Cap doesn't go all out against regular people and, because of that, also sometimes gets tagged by things he shouldn't, based on showings.
And I really don't get what the big deal is about Falcon. He has done nothing impressive so far in the films. Barry destroyed a drone with mounted machine guns (whose bullets he easily dodged) during training before, and WS has nailed Falcon with a grappling hook, so he can be tagged by someone as skilled as Oliver.
