As Joe Ross said, its best to do a robot map like this (pardon two year ago me's inability to write beautiful code) mainly for two reasons

1. Electronic configuration. If you're doing anything with the board than you can easily reference the ports in a clean manner
2. Code management. Its generally more beautiful to show what each specific number means instead of just throwing in random numbers in places

Of course, it's also heavily opinion based.
