As it turns out , in our family, we have 2 Cannondales, a Bianchi, a Specialized, and a 3 Treks. They are all good bike and serve their intended uses very well. I am 5'11" and ride the Cannondale (road), Bianchi (touring), Trek (road and mtn). All are 58cm. I suspect that you would be in the 56cm range, but it would be better to ride some different sizes to nail it down. I think bike fit is more important than brand or model. I ride my Trek road bike the most because it fits really well. While the Cannodale is a good bike and much more expensive than the Trek, it just does not feel the same. I think the Trek frame is a tad smaller, even though they are both 58's. Try before you buy (if you can) and go for fit. Good luck.
