Both have comparable strength, but Cap has far greater reactions from consistently dodging bullets and Ultron's sentries as well as keeping up with characters such as Mark 46 Iron Man. His shield can also damage characters far more durable than Raimi-Verse Spider-Man such as Ultron and Cap also has the advantage in actual combat experience/training. Needless to say, Steve takes this.
If this was End of Infinity War/Endgame Cap, then it'd be an absolute slaughter since he was somewhat relevant to Thanos and could keep up with him in a fight.
