I have a Giant Cypress and the bike does feel and fit larger than the sizing would indicate. I'm 6'0" with a 33" inseam and I ride the large model. I agree these bikes do feel big, however I have not had issues using the bike.
Part of the fit issue for you might be the 700c wheels. I would ride a selection of other bikes, including the Giant Sedona in a medium size. The Sedona has 26" wheels and this might be part of the solution.
