Everyone, except apparently John and Mary, was really worried about Sherlock making this speech. We're talking about a man who didn't realize he shouldn't be in the bride and groom picture, who will yell at crying old ladies and tell children there's no such thing as heaven. So it's not really surprising when everything falls apart and Sherlock starts monologuing about reason, logic, and petty emotions. Also how John sucks and he likes to have him around because he makes Sherlock look good. Then he gets to the doom of the human race. Light wedding stuff. But then, there's the turn. Sherlock has an incredibly rare moment of real self-conciousness, the kind no one thought he was capable of. He points out that, given how much normal people are put off by him, John has to be a pretty swell guy to like him. Sure, it's a bit too much about Sherlock, but it stills says something lovely about John. Sherlock really, honestly, tells John how important he is to him. Now, remember, Sherlock has locked John in a room and subjected him to tests of terror, he has ditched him about a million times, he has apparently drugged him into missing entire days, ruined dates galore, taken over the apartment, put heads in the refrigerator, and last but not least, convinced his best friend he was dead. So for him to step back and tell John "you are wonderful, you are amazing, and I am unspeakably lucky to have you" is a truly wonderful moment.
