They are more or less the same as far as running normal user code. They are programmed differently, so your programmer has to be able to handle A versus non-A chips.

Just a side note, I am using a PIC16F628A, but am programming it as a PIC16F627A.

This works, as the 628 has more memory, but roughly the same internal structure.
