I would rate them at an 8.  The selection is superb, the local distro center is maybe 20 miles away so 1 day turnaround most of the time, and the customer service has thus far been excellent.  Prices are lower now too.  They would have gotten a 10, save that now it seems that sometimes the shipping is irregular.  I'll have some titles shipped the same day, however the estimated arrival will be several days difference, as will the actual arrival.  I hypothesize that they are shipping the DVD's from across the country sometimes instead of locally.  Shipping has slowed down since the price decreases as well. 
The primary reason I've stayed with Netflix instead of switching to one of their competitors is that I don't typically rent the summer blockbuster hollywood garbage, I like to get a lot of older movies, sometimes an obscure title or two, and sci-fi TV series.  Plus I've had horrible experiences with Blockbuster's in store customer service, and I despise Walmart just on principle.
