I am very respectiful of the creator of fruit 2.2. and the way he has influenced
programing. Having said that, it looks to me that toga is similar to fruit, but
also clearly distinguishable from fruit in terms of how it evaluats a postion.

 Check out the stats here :

Unforutnately, there are no head to head comparisons of fruit and toga, but you
can look at how similar they are when competing against the same engine. For
example, togas evaluations  are more similar to ktula 7.5 evaluations than
fruits.

this is not definitive reasoning, unfortunately. Fruit went comericial between
version 2.1 and 2.2, and the new code was no longer public access. maybe the
observed differences are due to what was added in 2.2.   i.e., maybe fruit 2.1
is almost identifical to toga, but 2.2 is quite different? any data on this?
