My humble opinion:
-if will be a large production (hundreds of devices at least) it might
be cheaper with PIC12F629 but this is not sure, will be much cheaper
with an Atmel or some chinese microcontrollers
-for a beginner, programming  will not be easiest than a 555 with two
resistors, one trim, two capacitors and one or two diodes, all of
these will cost togheter less than a PIC12F629, that's sure.
