Your DVD rip is still probably better quality.
The features of your PC video player probably trumps whatever Netflix player you're using.
Your DVD rip is playable on just about anything including platforms that Netflix doesn't support.
Playing your local copy doesn't require any sort of external network and doesn't consume your 3G or your home Internet bandwidth cap.
Any task is going to be harder if you procrastinate until you have a huge mountain of work.
