PER is too much of an offensive usage stat and last season was probably LA's best statistic season so that's cherry picking. Both PER & BPM use box-score stats, but PER uses semi-arbitrary hand-crafted weights while BPM is more mathematically sound. Here is an article that analyses various NBA advanced metrics based on predictive power.

Here is the conclusion:
The best one-number metrics — BPM, PIPM, RAPM, and (probably) RPM — are actually quite good at ball-parking player value, but until we can generate more context-specific numbers, we’re still going to have to do the legwork of analyzing circumstances manually to filter out some of the noise. That, and maybe we can permanently retire PER now.
I used two different stats over the course of 4 years. The two stats I used put LA at 28th and 31st last year, nevertheless, taking 4 years into account LA only comes in around 60th.
My eyes work pretty good for evaluation. Stats are nice but seeing can be even more important. Pro leagues use to use this method a lot and were pretty good drafting . That and gut instincts have shown to be successful.
