If you're gonna turn them on and use them when parking, in tight spots, etc. then I'd say the top/side view cameras. Especially if you have a history of scraping wheels, etc.. Note, when starting the car you have to wait for the Nav to boot before video is available (up to 20 seconds or so). So if you typically jump in and drive off quickly the cameras may not be available to you. PDC beeps (audio) are available pretty much immediately.
Remember the top/side cameras require you voluntarily activate them.
