I have been a member of Netflix for about two years. I was lucky enough to get on the 2 movies out unlimited per month plan before they changed it to 4 movies a month. I live in Northern NJ while their distribution center is in New Brunswick, NJ. Turn around time has been awesome. I mail the movies back on Friday or Saturday and Netflix gets them on Monday. They will ship Tuesday's releases on Monday and 90% of the time, get them shipped on Monday and delivered Tuesday. Couldn't be happier. Either one probably does the same job. It all depends on where you are located based on the distribution center.
I think what would really help people decided is if someone started collecting where each one's distribution center is located. As I stated earlier, there is a Netflix in New Brunswick, NJ.
