I've read the +spiritbind stats aren't really worth it over just spiritbinding another piece of gear in that slot. The difference is negligible. The real bonus is spiritbinding HQ gear, socketed with some cheap materia.
I usually spiritbond crafting jewelry while running AK on my healer. Takes 2-3 runs to fully spiritbond, and I also get tomes for my time. Crafting jewelry will always net you a materia that'll sell for at least 10k, and 25k if you get the Command materia (+control). Helps that I have a 50 GSM to HQ the accessories easily and meld at least one materia into it.
