I use SDM mostly for the extended macro length for cast sequences, but I will say that in my opinion, this is far superior to Macaroon in that you are able to drag and drop your macros anywhere you like while in combat. I find myself having different macros for trash, bosses, phases during boss fights, etc... Not being able to have the freedom to move stuff around made me psycho. The sharing feature is also just about as cool as it can get. I respec'd my DK to blood just to try it out and my wife was able to send me her DPS macro straight into my character's SDM profile. SO EASY! Love this mod.
