Well, obviously. You already have it in your mind that this is the best fight scene, so you'd think of some reason why it was better, even if it wasn't.
A,N isn't perfect; the scenes with Cordy and Connor (and not just the last scene; that's just the worst) are a drag. The scene in Connor's shack, the alley...it just drags along. Everything else is good, yes, but it's definitely not the best Angel episode.
...and Wes taking out the shotgun is one of your reasons? Wow. That's deep.
