The advantage of using the ERASE CCW command directly (which is what the CA-1, CA-Dynam/TLMS, DFSMSrmm utilities all do) and something like IEBDG is the number of CCW's sent down the channel. With the ERASE CCW command, one CCW is sent and the device just humms along for 30-45 minutes doing its thing. So other devices on the same channel don't have any contention with all the x'ff' or x'00' going down the channel.
Of course I would STRONGLY recommend you check your MIH values before doing this. The manual gives you the values you need to specify for 3590's. An extended-length 3590 on a 3590-H drive will take a good solid 45 minutes for this one CCW to complete; which is usually longer then the default MIH values you probably have specified.
