I had Netflix for a year and was very happy with it. I was getting approx. 14 movies a month. I then heard that Blockbuster was opening up an online warehouse in my area so I switched to BB ($17.99 plan). I was getting about 24 movies a month(plust the 4 in-store coupons). I have 1 day mail service in my town so the turnaround is 3 days.(mail one back on Monday and recieve another on Wednesday. However BB has started slowing the dvd's sent to me. I will mail 2 on Monday. They recieve both on Tuesday morning and only send me one that day and then the other one the following day. I have 150 movies in my queue. Even with the intentional slowdown I still receive over 20 movies a month. Don't forget the 4 in-store rental coupons that BB gives.
In summary; find out where the shipping warehouses are for BB and Netflix and how close they are to you address. If you have one close to you you might try them first. Remember that the BB in-store coupons are a bonus. I use them when a new release is not available.
