Hmm, this is a tough choice. All three are pretty impressive biotics and all three are also known to be rather ruthless (Jack and her criminal origins, Aria being a crime lord, and the Justicar code for Samara). If I had to choose, I think it would probably be Jack. She seems to be the stronger of the bunch, at least in terms of biotic potential.
