Would I use free weights exclusively? Yes. The workout is second to none.
Would I do both if available? Again, yes. Using the machines for variety is great if you use free weights a lot and need to break a rut, or if you find a machine that moves in a way that can't be duplicated with free weights.
Would I use machines exclusively? Not likely.....
If I had only a single option, I would choose free weights- most bang for the buck.... sounds like you have a choice, though.
But that's just me...

The most important thing is ballance and stability, you lose this with machines because your path of motion is already dictated to you, there is no reason for your stabilizing muscles to control the weight.
Machines do have there place though. Example a
dumbbell fly is a very inefficient way of working the chest, the exercise is the hardest when the muscles are very weak, so you will fail in your weak point before your strong point (the farther away the weight gets from the pivot point, the heavier it feels like on a see-saw, your shoulder is the pivot point and the weight is of course the dumbbell.)
Nautilas came along and made somthing called a "cam." It is that wierd kidney shaped thing that the cable raps around, it is attached to where the machines pivot point. This was made to match the muscles ability (muscles are weak when fully stretched, strongest in the middle, and then weak again at the end), you will notice that as you do a rep the kidney shaped thing causes the cable to either get farther or closer to the pivot of the machine, this makes the weight either harder or easier. So if a pec dec fly machine has a good cam profile where the cable is close to the pivot point at first, then gets farther away and ends up close again, it can be much more effcient than dumbells. However for exercises like
skull crushers and standing bicep curl the design of your body matches up perfectly with free weights.
I totally agree with Tuna, I would use free weights exclusivly if I had a choice between the two, but both if I had the opprotunity.
