Ball and spring MBCs block boost from getting to the wastegate, which helps it keep from opening too early. The main advantage of electronic setups is usually to running different duty cycles at different RPMs to help overcome boost drop or to have realtime feedback and have the controller shoot for a target boost level. Most electronic setups are not all that advanced though and don't have RPM specific set points or do a horrible job of realtime feedback on high boost setups.
