Re: "She can still outrun us, and outgun us."
I am a firm believer that the statment refers to the amount of battle damage that the Enterprise had sustained. I don't think that a Miranda class can "outgun" a Constitution class, though perhaps "outrun" might be an option since the ship is smaller. There really is no canon reference, so anything is just speculation.
