As I noted in the Github Readme, this tool will not generate code that you will able to REcompile. My tool does a lot of things, but straight-up repackaging/ripping off other people's apps is exactly what apk2gold is bad at.

Decompilation to java is still a lossy process; if you want a non-lossy process you can check out APKTool which will encode/decode Smali (a Dalvik VM representation/assembly lang). But then you have to learn Smali...
I would say that V10S is for small modification/hax, and java decompilation is for understanding how people did things/what they are doing.
Also becoming a smali god is hard.
