Well, if it makes you feel any better, Dobson is the voice of Starscream in Armada, Energon and Cybertron. Between Dobson and Parker, I prefer Parker as he actually tries to emulate Latta's style. Parker says he learned how to do his impression by actually studying Latta during their time together on GI Joe (Parker was the voice director during the DiC series). So he's got some pretty good experience; he learned from the best. His Cobra Commander impression is also really impressive.
