KT200 or TagFlash?

Read/Write ECU:
TagFlash will read/write more ECU than KT200 (for example, Delco E84, md1cs018, dcm2.7ap by removing ECU, sid208-sid209 on Bench, dcm7.1b via obd, dcm6.2v via OBD. )  

For some ECU, they both can work but in a different mode; (for example, TagFlash R/W sid807evo on Bench mode , KT200 R/W sid807evo in Boot mode or pinout mode) 

Both KT200 and TagFlash read/write ECU for car/truck/tractor/Marine/Motorbike in the method of BENCH / OBD / BOOT / BDM / JTAG.
