I can't say I was blown away. I have the 9th. I think you should take a look for yourself and see if it will make a significant addition to your reloading library.
Take a look at the user images on Amazon, someone posted a pic of the rear cover, which details some of the additions. It also comes with a card giving access to their loading software (1 month? 3 months?). I haven't used it yet.
One thing they purport is more load data for powders newer to the market, like Shooter's World, but I would have to say they still don't have much in that regard. Something is better than nothing, I suppose.
I'm not trying to slam it, it is a good manual, it just doesn't add that much for my purposes.
