If $$$ matters you need to check both of them out. $119 vs $399 is quite a difference. SD3, if you like to rearrange mic placement, etc, etc, etc.
Ez drummer 2 is simple, sounds great but has LESS user functionality. IMHO, if you go by your orig post, Ex drummer 2 would suffice.
You still have control over overheads, room ambiance, etc, etc.
**Also, probably ca find specials on both of them if you look around.
If $$$ is not an issue, well then you have a choice to make. I have been happy with Ez drummer 2, but I do have steven slate platinum drums also.
You should check out the functionality and see what you think you will actually use. Then again, I am just a guitar player.
