Ok, I've looked through both of these. In my opinion, the 360 labs are so much easier than the INE labs.
The 360 labs are very "Drive into town, turn left at the third stop sign, park so you're not blocking a fire hydrant, go into the store, buy a loaf of rye bread with exact change, and then come back home without driving on Maple Street".
The INE labs seem to be a lot more "Go buy some bread. When you're done, you'd better have exactly $.83 left in your pocket. And that bread had better not be white, wheat, or sourdough".
Khawar Butt's book is also a whole lot closer to the 360 approach than the INE approach.
Which is more like the real thing?
