Purely as a standalone apple, the Granny Smith does NOT (in most opinions, it seems) hold its own against other apples. A 1v1 challenge against some of the more popular apples seemingly places the GS as the loser.
However, you mentioned the pairing and combinational use of the GS, which is where it shines. Granny Smith is meant to be dipped, diced, baked, smothered, cheesed, etc. The GS goes way up in rankings, when you pair it with other foods.
I think that's why GS is low on the rankings. It's probably getting a bit harsh of a review on that site, I grant you, but again I don't think it holds up as a standalone apple quite the same as others.
