I think it's a great work.
Some of the parts of the sections from other pythagoreans are quite patchy and a tad too religious. The Golden verses are pretty great, it's kind of a how to guide for living a good and wise life. You'll find some are similar to common sayings or christian preachings, they are probably things that people have been repeating to each other since language began.
The best part for me is the symbols of pythagoras which are cryptic sayings that are alternately baffling, mad as a box of frogs, truly thought provoking and maybe even genuinely useful. For example -
cut not fire with a sword
departing from your house turn not back for the furies will be your attendants
walk in unfrequented paths
eat not beans
Sacrifice and adore unshod
Each saying has an explanation after it, which is usually quite wordy but tends to throw light onto even the most bizarre instruction these are by Iamblichus, though this edition doesn't really make this clear. The main failing of this book is that it seems like something that was just grabbed when it went public domain and printed off with little care to properly format or explain what it is. A better book in this regard is the Pythagorean Sourcebook by Guthrie, which I read after this, even though it still has pretty much the same golden verses. That one is more expensive but well worth it, more symbols, some biographies, a nice essay, some various pythagorean fragments.
This one is still worth reading, if you just want the verses and the main symbols, quick and easy, but then so is just checking wikipedia.
