I have absolutely no idea what you just said. Cap was revived in 1964, in Avengers #4. He has been Captain America ever since, or at least fighting the good fight. Panther didn't even come out until well after Cap's revival, so I have no idea how you reach your conclusions. Panther was not some "lethal" combatant until AFTER he took the herbs, where he began to gain his abilities, again as described and shown in the Avengers. He was a trained fighter, but hardly in the range of "lethal combatants" up to that point.
Now I fully understand that Comic book years are not the same as regular folks years, but the fact remains that all of the battles Cap has fought have occurred in his "lifetime", and these are FAR more numerous than Panther's. If you recall, Panther himself dropped off the radar for many, many years after he left the Avengers, and has only recently been resurrected for a new generation of comic fans. So, according to your logic, remove ALL of those years from BP's history of learning and honing his skills in real combat, while adding up the years that Cap was at the forefront of Marvel Comics appearing in his own books, as well as the Avengers and guest-starring in several others, and Cap's experience FAR exceeds BP's.
You people should know that if you're gonna mess with an icon, you're gonna have to bring something besides half-truths or bad math to the table to beat him. Cap wins. 😮💨
