Both are going to be very fast relative (seconds) to the other work involved (days, months) so it is a moot point. Sometime you are going to have to get the bootloader program onto the chip so some sort of programmer is required. If your project is going to have a serial port on it anyway go for the bootloader, otherwise use the ICSP.
