I have Ezdrummer 2, Native instruments Abbey Road modern drummer and Addictive drums 1 & 2 (with almost all midi and extension packs)
I think that Ezdrummer 2 is even better than Ezdrummer 1. I was almost ready to upgrade to Superior drums (using Ezdrummer license) when Toontrack released the new version. No regrets so far!
Addictive drums 2 is very good too (and I am already a user for a long time) . It is good to have more than one option, and XLN Audio is a cool company (excellent products and support).
