depends on your experience. SS covers the squat, bench press, deadlift, standing press, & power clean in detail, is well-reviewed & has a nice beginner's routine, but I already have McRobert's book on technique so I D/N bother. PP is very good, though I feel it could have used more specific examples of intermediate routines.
Rippetoe was also supposed to have a new book (Basic Barbell Training?) out last month. his books are good, no frills, and succinct.
