I am using Roger, but I also have all of Gleim's textbooks. They were given to me for free by an old accounting instructor. I can't make a comment overall about Gleim's program as I have no access to the online portal. I'd say the Gleim texts are good for most topics. They are a little stuffy and stiff at times, the MCQs are harder than Roger's but there are more TBS questions in each chapter. And, they have clarified some things for me that Roger gave rather muddy explanations of. Or, let's just say that they have been good as a “second opinion”-type source.
Roger is good for most people. I like it. The lectures are good and keep you motivated. The text is good but contains a lot of info that you really don't need (Gleim's is much more concise on many FAR topics, I've noticed.) Roger's MCQ are very much like those you will find on the exam, but the explanations for each question are often miles long and shouldn't be.
I know a lot of people on here buy the Ninja products. I'm sure they are good but I'd say that whatever review course you have, I think they all provide enough MCQs to practice on and only after you've totally exhausted those and still feel like you need more, then buy them. Or, just buy Ninja as your review course and that's it.
I don't think I'd recommend any particular review course to anyone. They all have their faults; it seems like Becker has a ton of faults nowadays (sky-high price for only 18 months was why I didn't buy that one; Roger was 2 years for like half of Becker's price.) As I said in my Yelp review about Roger, “it's probably the best one out there, with the least amount of faults.”
Hey, is there anyone on here who uses one called Surgent? It's newer in the market – they do offer half off if you can prove that you flunked all the sections at least once on Roger/Becker/any other review course and can provide printouts of your scores and receipts.
