Is GameFly worth it?

Right now, I got a subscrition from BlockBuster, just because it was a free month trial. I had it for like 3 weeks now. And, basically every game I get plays bad, scratched so it's full of glitches (I'm currently playing The Force Unleashed II, and it freezes now and then for like a minute), and basically ALL the games in my queue are unavailable either for a short time or a very long time, and considering its been 3 weeks already, I'm assuming a "short wait" means "VERY LONG WAIT." And games that are new releases aren't available until 4 or 5 months after their release.

So, is GameFly exactly the same, better, or worst? I want to hear your opinions.

Also, here is a screen shot of the things in my queue. http://img214.imageshack.us/img214/6043/blockbusterqueue.png
