random Holmesian thought

The fundamental difference I see between ACD and BBC Sherlock Holmes: I can't imagine BBC John saying "the best and wisest man I have ever known" about Sherlock, at least not without a heavy dose of sarcasm. ("The most amazing and most brilliant man I have ever known", yes, but best & wisest, no.)

Granted, ACD Watson says this after having known Holmes for about ten years; he likely wouldn't have said it right after "A Study in Scarlet". And it's anyone's guess where BBC Sherlock's character goes in future seasons; for all we know, he'll reach that point.
