At the end of the day, I ended up with a 58, because I felt a little neck strain with the 56. I'm personally glad I went with the 58. I sit up tall, to be certain, but I love the relaxed fit (I'm almost 59). I shortened the 100mm stem to 90, it didn't really affect the handling characteristics.

I also have a Giant Defy 0, M/L, which is probably the equivalent of a 57 cm. Definitely lower up front and a bit more aggressive fit. I love both bikes!!
