Summary : I own Jang RHEL6 and Ghori RHEL7 (Jang RHEL7 is not yet released at the time of this review. I plan to buy it before taking the RHCE test and to refer to the PDFs afterward). I find Jang6 better on intangibles (paper quality, diagram readability, fonts/headers, greyscale text) and on tangibles (exam readiness checklists, index, PDF copies, an extra bit of technical detail). Ghori seems perhaps to have a better grouping of information, which may lead to better information recall since similar information was learned at the same time.Here's a quick random comparison of the two on /tmp and tmpfs. Jang6 says 'tmpfs is a virtual memory filesystem using both RAM and swap.... (in a different section) /tmp files are deleted periodically by default'. Ghori says '/tmp is virtual; used by running programs and program installers, files are deleted at reboot'. Both have good info. Jang seems more complete, but Ghori has all that you'd need for to past the tests including (as both do) practice tests.Another reviewer writes: "the lack of PDF is a bit of a drag." To me, this is a huge difference. Jang manages to publish PDFs and remain highly profitable / the industry standard. The searchabilty of an electronic copy is infinitely useful when you're using a non-sequential reference book, especially when Ghori sports such a thin index (9 pgs of indexes to 700 pages of material). And a PDF is more universally available - I can keep a copy on my tablet for reference anytime, anywhere.If you can only buy one book, I would speculate that the extra time it is taking to prepare Jang's book is a sign of extra work that goes into preparing it. Of course, I'm comparing an existing product with one that does not yet exist, so who knows?
