As I've said before, I personally have never used Cava Packager, so I can't offer an opinion on whether it is good or bad. I have seen others recommend it in posts on this site. In my personal experience, I have not had any issues using the pp utility from PAR::Packer to create executables.
If you use the pp utility, be sure to read the documentation. You'll probably want the -x option and might want to read about the --gui option.
From my perspective, it looks like you have a choice of two tools to use. Go with the one that both gets the job done and that you're comfortable using.
