**Note, simply personal preferences listed below. I honestly don't think it matters too much one way or another.**
Honestly, unless you're planning on multi-classing into a class that requires a specific alignment (Pally, Monk, Barb, Bard), I prefer true neutral. The ranger/monk splash is pretty popular, so obviously you'd have to be LN or LG for that build. Bards and rogues may as well be TN since they can UMD everything anyway, ditto with sorcs (even at half ranks).
