Latest and greatest diy 9mm PCC?

So I have been mulling over what potential PCC to try and build. There are so many options out there, FGC-9, Rebel 9, DB Alloy, and PWC-9 are just a few I have stumbled across. What are the most popular builds? To be a bit picky, I have a surplus of Glock magazines, so a good that takes Glock mags is preferred over making mags from scratch. Which is the “latest” release with the easiest to understand documentation? And what have been your favorite builds in this category?
