Performance-wise? There's no difference
Flexibility-wise? Well, if you put your swap partition on LVM, then you
can move it around and extend it just as easily as you could a file.

Perhaps the only advantage a partition has is that you can fairly easily
ensure it's at the fast end of your disk (that said, balance up how long
the head's going to be there, with how long it takes to get there).

A partition is probably the most common.
