Well, I use Love film Bjay, but have just downgraded. I pay £7.99 a month for one disc at home at a time, and then unlimited streaming of films online (Say, to play on a laptop, or ipad, or anything you can stream on). I was on the £9.99 a month one, which is 2 discs at home, and unlimited streaming. But you can stack films in a list on your account, and as soon as you've returned what you have, they post the next ones out straightaway, all free. I really like it. 
I've never used netflix, so can't comment on that at all I'm afraid.
