'Compared to' and 'Compared with' are both idiomatically correct. The usage depends on the context of the sentence.
- To compare to is to point out similarities between objects regarded as essentially of a different order.
- To compare with is to point out differences between objects regarded as essentially of the same order.
For example:-
1) She compared her work for women's rights to Susan B Anthony's campaign for women's suffrage.
2) His time was 2:11:10 compared with 2:14 for his closest competitor
Furthermore, 'In contrast to' is generally preferred to 'when contrasted with' in GMAT, though both are idiomatically correct. Hope that helps
