For ECU programmer. FGTECH, mpps is more stable than K-TAG. K-TAG is more stable than KESS V2. For mpps, it only work on ECU via OBD, so not need remove ECU. For KESS V2, work on ECU via OBD, BDM, BOOT mode and so on. For non-obd method, it needs you remove the ECU or do other things for the car. So if you say mpps is easier to use than KESS V2, reply is yes.
