I have lots of free time at work and use both but am contemplating losing one.
I have been using Netflix since 2003 and feel a loyalty to them. I have had pretty good turnaround with them, a lot of times get new releases on the day, have a huge selection of indie movies and only lost (in the mail) 3 movies over the years. But...
I really like Blockbuster and being able to go to the store and pick movies out when I am done with the ones I got in the mail. But sometimes with the ones that are only 2 days I don't get to watch them cause I get busy.
