ECU Programming Tool: FGTech Galletto V54 VS. K-TAG

I was very confused about two kinds of the ECU chip tuning tools that I found online recently, i.e. FG Tech Galletto 4 V54 and K-TAG master V2.06. Once I bought from Aobd2shop, so I decided to ask the engineer to make an analysis for me.
As for these two kinds of ECU chip tuning tools, the engineer has compiled a short guide for my reference.
