This new version of Cap is absolutely great. Moving away from the Avengers tribe and into S.H.I.E.L.D. comes with perks it seems. He has the statline of a 3-cost ally - 3 HP and 2 in stats. However, he comes with Toughness, which instantly makes him much more valuable. You can defend twice with him - the round you play him on, then THW/ATK twice and defend a second time on the fourth round. But he also comes with a ready-effect, which is at least 2 more THW/ATK from your hero or another S.H.I.E.L.D. ally. There are tons of synergies to be had, whether it be readying Agent 13 to then ready another support, or accelerate the use of the Bambino in the hands of another Shield operative. You will do well to enlist Captain America in your aggression deck with a S.H.I.E.L.D. hero.
