SSD EX or EZDrummer?

AdamG94 I would say go with the EZDrummer. Personally I like it much more than the SSD EX. It's very simpler and it sounds better to me.
 
Just to throw in two more cents: I prefer the EZDrummer sounds quite a bit over the SSD sounds. The Drumkit from Hell expansion (really, it seems like EZDrummer and the DFH have become almost intertwined)is solid and can be eq'd and processed a bit more than it already has been. The new Metalheads expansion sounds REALLY good to me.

I guess it's just me, but the SSD sounds from their audio demos at their site just sound like a toy, not like actual drums.
