Couldn't tell you how they are in comparison to BJJ manuals, but I picked up Lawrence Kenshin's book that just came out. Its awesome imo, really helps break down techniques into small digestible chunks. I will say the technology side is a bit wonky, took me a bit to get it to work. It is designed for Apple computers and really shows if you are using it on a different device. That being said, its currently loaded onto my PC, Laptop, tablet, and phone lol. Lawrence was a great help in getting my technical issues solved, and responded quickly to emails. You can check out some of his videos on YouTube, and I would also suggest looking through Sylvie Von Douglas-Ittu's YouTube channel. Sylvie's stuff isn't setup like an instructional, but I don't think anyone has more online training footage out there than her. I've learned tons of things just by watching her posted sessions with private instructors.
