I don’t have to worry about people talking or making noises and disrupting the tuning process

Any extraneous noise that vibrates guitar affects it in vibration mode

I guess it picks up the vibrations directly from the head of the guitar and ignores ambient noise

so extraneous noise does not affect it

Not as accurate as I

As a basic tuner it's ok but not as accurate as I

(over/under) a perfect low E or A. use the 12th fret harmonics to tune if you're properly intonated and you should be fine
