Yes but Rage is protecting you from all the other BPS damage you are taking in that encounter or throughout the day, so it's still not really apples to apples.

And sometimes you are using Reckless Attack when enemies already have Advantage. My barbarian, right now as we speak, is currently in a life or death battle against a pack of wolves, backed up against a tree lol. He's using Reckless Attack and it functionally has no drawback in this case because of Pack Tactics.

Not to say your observations are wrong, but the game is really more complex than our comparisons can capture.
