I've been running a Lovefilm free trial against my old Cinema Paradiso subscription. The LF turnaround of discs is faster than CP. Not by much, but I think it's been post one day, receive and send new discs the next day, every week throughout the trial.
CP is more variable, sometimes turning around in 2 days (same as LF), sometimes 3.
I certainly intend to stay with LF and cancel CP when the trial period enRAB.
