Yes I agree it is worth every penny. It is a fantastic product and all your EZDrummer kits are compatible. It takes all the great features of EZDrummer, simplicity of operation and so on but also much better drum sounds. You can also easily edit the MIDI within SD3. Toontrack have made a really sophisticated product which lets you control just about every area but also made it very user-friendly. It is a huge download but you don't necessarily have to install everything. There are features for surround sound etc which I didn't require. I just installed the basic sound library and the room mikes. I didn't bother with the surround set up, height surround or additional bleed. My install therefore was a mere 80 GB!

I have not used EZDrummer 2 since having Superior 3
