Seriously I don't think there is much difference between the two. I'm sure you'll be happy either way.
For some reason I like the CANNONDALE Bad Boy Fatty Alivio Disc 700c. I don't know why though.
FYI, I love my Badboy Disc although a few things broke during the first 1.5 to 2 years. They were the avid components which neither of your bikes have. My cannondale seat post snapped (C4) and I'm only 60kg. It snapped where the two pieces join. That's ok because I replaced it with a one piece post. The seat post clamp also wore a hole through where the bolt rubbed. I think Cannondale has changed that clamp on your choices.
