I think that it is hard to compare.

Fruit has probably better evaluation and better search than Crafty but Crafty
has better opening book and learning(fruit has no opening book and no learning).

I think that giving fruit an external book is not fair because opening book is
part of the code of Crafty when fabian did not write code for opening book.

Fruit also does not support parallel search and the code of Crafty support more
than one processor.

Not using more than one processor for crafty gives fruit unfair advantage
because it is possible that Bob Hyatt could do better by spending less time on
supporting more than one processor.
