While these are excellent books, arguably better to learn from than Schiff's, they aren't the best answer to the poster's question. Goldstein:
a) was the classic American grad text for generations
b) had virtually no competition in its heyday
c) was eventually joined by numerous other excellent texts
d) now seems dated in many areas of presentation and in breadth of coverage
and now, because of c and d
e) is no longer the first choice for classes nor is necessarily the best to learn from.
I claim that only Schiff's Quantum Mechanics text mirrors all of these traits.
If you want the best book, then that's another thread!
