It sort of depends on your location, what you need to learn, and what you're interested in. Kochanski's Northern Bushcraft is by far the best for the boreal forest, and arguably still the best all-around book due to its focus on axes, knife use, fires, and easy shelters. There are no better chapters in general bushcraft books than what he has on those subjects, however, the fire and shelters sections might not be that useful outside of the boreal.
But buying his book along with another book like "Shelters, Shacks, and Shanties" would be better than any other general book. And you could look up information on fires for your area. There's just no one else who has written so well on knife and axe use (safety especially) apart from a specific resource like "The Ax Book".
Lundin's 98.6 is good, but his writing style and humour can get annoying (and most of what he says is from him being a student of Kochanski, who is a straightforward old-timer with no fluff/bullshit). Ray Mears Essential Bushcraft is pretty good. Joe O'Leary's Wilderness Survival Guide is also good, but more British specific. Woodcraft by EH Kreps is probably the best for traditional camping styles. (Although I haven't read the Angier book yet, and it is supposed to be a classic.)
