Quantum Better advanced Quantum Mechanics book than Sakurai?

[Elaren]

Sakurai's Modern Quantum Mechanics is 1/2 of a very good graduate textbook. Unfortunately Sakurai passed away midway through writing it, and it is very obvious exactly where it swapped from their writing to just using their notes. The back half of the book, while by no means bad, is notably less easy to follow. I was wondering if anyone had a recommendation for a textbook covering the same material at the same level that has a more constant quality thorughout, in line with the first 3 chapters of Sakurai.

Try Leslie Ballentine's "Quantum Mechanics - A Modern Development".

The two things I like most about Sakurai is his style of using the simplest way to make his point and his little insights which aren't highlighted as much in other texts (his treatment of basis vectors in the different pictures and the relationship between symmetry and degeneracy come to mind).

Ballentine doesn't reach Sakurai regarding the first thing (I don't know of a book which does) but he has plenty of the second (non-relativistic space-time symmetries, rigged Hilbert space and interpretation come to mind). His approach is more formal and deductive than Sakurai's but still very well-grounded in the physics.
