Agree with @minismom. I am sticking with Becker as my main study materials. Since my Becker materials are pre-2015, I am supplementing it with Ninja, Wiley & various cpa review provider videos.
Roger's videos are definitely on top of my list. You can watch him for hours without falling asleep. Tim G. & Peter O. are alright, at least they are also fun to listen to, Like Roger P.
Overall, both Becker and Roger CPA review materials are meant for those who like to use their materials for a while, at least until they passed.
In fairness, I haven't really fully used Ninja/Wiley materials each time I purchased, at least since 2015-March 2017 for Ninja and 1999-pre-2016 for Wiley. I always run out of time. I like the SIMs part, which I can briefly make notes out of them.
Also, I haven't really listened to any Ninja's audios either (except for Economics/Indv. Taxes), so I cannot say much about it. Bisk videos are great, especially FAR. However, you have to take notes while listening to them, which is one thing I missed while my subscription was active.
I have been accustomed to Becker's textbook, so I never really purchased and tried reading Ninja textbook. I don't know what's in it. I heard a lot of good things about it though.
For now, I am happy with my review materials. If I ever need to purchase additional materials, I might go with Ninja for its MCQs/SIMs app. It's great for MCQs & SIMs practice (if you have time), especially building up speed for calculation problems, and making notes with its SIMs.
Becker vs. Roger? They are both good to have for CPA Review materials (if you can afford it), either one is fine.
