K-TAG & KESS V2 ECU Programming Tool, which is better?

My friend intended to buy an ECU chip tunning tool. K-TAG and

KESS V2 put him into a dilemma. He turned to me for help because

he believed I have more knowledge of ECU tools. I found recently

many people talk about this topic as well. Thus I made a simple and

direct comparison for him.
