Conclusion of my review:
Editing and formatting is okay, but not that great - there are quite a few editing/formatting glitches to be found herein, sometimes acting as slightly detrimental to the rules-language. Layout adheres to RC's per se beautiful 2-column full-color standard and the pdf comes fully bookmarked for your convenience. The full-color artworks are almost universally completely awesome. The hardcover book's cover-artwork is not as blurred as the one of FaSB. Paper is rather thin in the physical version.
Lou Agresta, Tim Hitchcock, Tom Knauss, John Ling, RA Mc Reynolds, Rone Barton and Greg Vaughan are all talented designers and authors and it shows in the compelling narratives herein, in the setting-flavor that oozes in buckets from these pages. In the brightest moments, this guide indeed captures well the flair and panache of Razor Coast and showcases their capabilities. Unfortunately, that does not extend to the whole pdf - there are quite a few issues with the rules-language herein, filler-feats, massive issues with the Yohunga base-class... all of those accumulate.
Another issue would be that this pdf endeavors to be a player's guide and partially succeeds at its goal - at the same time falling flat of guiding players regarding the tone the campaign shoots for, which approach (as per the RC-book) to take etc. - if one player shoots for a Disciple of Dajobas, another for a Tulita and a third for essentially a colonialist pirate, as a DM you have an issue on your hands. Especially the former class does simply not belong in a player's guide - or at least requires a massive caveat. As a sourcebook, it fares slightly better, though e.g. the decision to include the player-material indulgences in the campaign setting instead of in this book should be considered slightly unfortunate. Personally, I also would have loved to see a slightly tighter synergy with FaSB, but that's okay and just a nitpick on my part. In the end, the Freebooter's Guide to the Razor Coast makes for a valid companion for a RC-campaign, but one that should see careful DM-oversight due to some problematic options/balance-concerns (*cough* Pele Liberator /*cough*).
In conclusion: Some light, some shadow - a mixed bag - final verdict: 3 stars.
