Components are fairly similar on the 3 bikes.
The Cannondale and Raleigh have a little better fork.
However you can upgrade the Marin fork to the Suntour Raidon which is a much better fork than all of them for $189 shipped directly through Suntour using their upgrade program.
Really the best advice is to ride them all and see what you like. However if your budget is $889 (the price of the C-dale) I would probably lean towards the Marin and and use the money saved to take advantage of the upgrade program through Suntour and get their Raidon fork.
I am assuming you are buying from REI since all 3 of those are bikes they carry. The good news is that if you are and you don't like what you get, you can return it.
