compared to - comparison within similar subjects -- children
compared with - comparison between dissimlar subjects

However, on a second thought, I am unable to find compelling evidence about the difference between 'compared with' and 'compared to'...

First of all, I feel the compare with and compare to thing you have mentioned is opposite.
But However, that is no more valid now on GMAT. I mean both compare to and compare with are correct when a comparison is being made of any type.

The answer is B
Compare to - is used to liken two things or to put them in the same category. You should use "compare to" when you intend to simply assert that two things are alike.Use "compared to" to illustrate that two things are similar

e.g -

1). The economy can be compared to a stallion charging at the gate.
2). I compare getting comments from students in class to pulling teeth.
3). She compared her work for women's rights to Susan B. Anthony's campaign for women's suffrage.

Compare with - is used to place two things side by side for the purpose of examining their similarities or differences. Use "compared with" to illustrate the differences a comparison draws

e.g -

1). The American economy can be compared with the European economy to note how military history impacts future economics.
2). It would be interesting to compare Purdue with Ohio State.
3). Ann has a 3.5 GPA, compared with Jim's 2.9.

Hi,
There is no difference between 'compare to' and 'compare with'. Both A and B are correct.
