Better typologists...?
Isabel Myers (INFP) took the 8 Jungian* cognitive functions, observed people around her, and came up with the MBTI. Pretty impressive, and not unrelated to Fi vs. Ti, I'd say. She used Fi to get inside the head of people very different from herself and extrapolated patterns with Ne.
Keirsey (INTP) then noticed that her SJs and her SPs were more similar than her STs and SFs, but that was also based on previous four-fold typologies. And he is too simplistic and schematic, wanting people to conform to his system more than they do, whereas Myers is more fluid and nuanced. I'm much more impressed by Gifts Differing than I am by Please Understand Me.
I am also impressed by Karen Horney (INFP) who, like Myers, observed people and figured out a meaningful
typology.
I'm not saying that I refuse to believe that NTPs could typologize just as well if they put their mind to it; I am just not aware of examples.
* Before someone mentions that Jung identified as INTP, let me state for the record that I believe him to be an INFJ.

Also, better fiction writers...?
Obviously this is a matter of taste (and I share Fi and Te with the NFPs), but personally I took less pleasure in reading Orwell (ENTP) and Kafka (INTP) than Mark Twain (ENFP) and Shakespeare (INFP), and if I had to forgo a reading experience, I think I'd rather erase xkcd (INTP cartoonist) from my memory than Calvin and Hobbes (INFP cartoonist).
(FYI I'm not totally partial to the NFPs. When it comes to comedy, I gotta go for the cold wit of the NTPs over the silliness of the NFPs. I'm hard pressed to think of an ENFP comedian I prefer to just about any ENTP comedian.)
And I can't even come up with any NTP poets to compare with Blake (INFP) and others.

Finally, how about better actors...?
Even when they play variations of themselves, NFPs strike me as having better projection of emotion whereas NTPs are more wooden. Johnny Depp (INFP) vs. Sigourney Weaver (INTP). Robin Williams (ENFP) vs. Sacha Baron Cohen (ENTP).

Just my two cents (as the INFPs would say).
