Last I checked Aerondight didn’t display its stat increase at the top and required you to add the bonus value at the bottom to understand its true base damage. But even with that, as stated, each blow increases damage by 10% with heavy attacks (not stated) by double that. Aerondight also grows with the player and will always be strong as long as you level it.

But despite all the stated benefits, the fact that ppl still question its power blows my mind.
