I'm in the middle of Roger Audit right now, and so far I think it's great.
I used Wiley for FAR (supplemented with NINJA MCQ + GLEIM Test Bank – doing the same this time around), but having seen a few of the Wiley lectures for auditing and accompanying text guide, I don't think it would have cut it for me so I went with Roger instead. I never used Becker, but with Wiley, there were numerous lectures plotted out for your day-by-day schedule for you to complete depending on your test date, study hours per week etc. Roger isn't like that, as there is a general outlined week-by-week study program which I suppose is their recommended schedule. The first 4 chapters are pretty heavy with lots of material, so it might take longer than their plan to complete them, but even if so, you'll catch up mid-way as the material and study text are much shorter. That's not to say they're less important, but it takes less time to get through them at least.
Regarding his lessons, I find him informative and entertaining enough to keep me engaged, and the text seems detailed/informative enough. I say “seems” because I have yet to take the test, but judging by the NINJA & Gleim test banks I've been mixing in Roger looks to be sufficient. That and quite a few other users recommend him. Either way best of luck!
