There are two aspects to this.
1) the camera shutter has a mean number of actuations before failing--and it is far greater than you can use--with either camera. Of course some fail earlier, but see 2).
2) Problems in the manufacture of a unit tend to show up early.
Given these I think it is a wash, and possibly the greater number of actuations is better.**
Of course new is better, but only b/c there is a warranty.
Not the same, but I am certain w/ lenses a more/well used sample is better.

** Certainly for the price difference I would take the less expensive one.
