You seem do dislike the QM sequence on LW.

Actually, there is a subsequence which is pretty good: {An Intuitive Explanation of Quantum Mechanics}(http://lesswrong.com/lw/r6/an_intuitive_explanation_of_quantum_mechanics/).

is there anything that would offer the same utility that the QM sequence offers, but in a better manner?

Well, Deutsch's The Beginning of Infinity is consistently praised by practicing physicists and quantum information researchers, and it advocates MWI quite forcefully. There is a lot of speculative stuff there which is best read critically, just like in his first book, The Fabric of Reality, so it is a good exercise in recognizing when you are being fed a teacher's password.
