To my ear, the verb version and the noun version are interchangeable. "To compare" is "to make a comparison."
I compared A to B.
I compared A and B.
I compared A with B.
I made a comparison of A and B.
I made a comparison between A and B.
I made a comparison of A to B.
Comparing A and B, A is larger.
Comparing A to B, A is larger.
By comparison, A is larger than B.
A, compared to B, is larger.
A, compared with B, is larger.
Compared to B, A is larger.
Compared with B, A is larger.
(Some of these may be a tad lower register.)
