I think it depends somewhat on whether you're planning on playing or running? I ended up buying the Bestiary's 2 & 3 next after the core group, but that's because I run for my family and more monsters to fight was more useful than more character choices.
Ehh....there's 350 monsters in the Bestiary Number One. I think that should be enough for me, and it matches up perfectly with the Bestiary Box, so I never need miniatures. To me it's not about what the monsters are, so much as it's about what you DO with the monsters. How much character the monsters have, and so on. I feel if my players want more options in terms of monsters, there's a massive amount of resources for me to get more monsters from, including stat blocks, that don't require me to spend 40 bucks on a new tome that offers no real new rules and numerous amounts of re-tread monsters, or even ten bucks on the PDF.
As for my playing situation, I'm the only of y group who owns rulebooks and other supplements. They have their own dice, but that's about it. They rely on me to provide them with ways to play, so it's a fine line I balance between providing options for them as well as for me. I would LOVE to actually be a PC one of these days. But for now I' saddled with the DM position. It's actually become damaging to me in a way, because I feel I could be a much better DM if I was a PC once and a while. I am using Golarion as a setting, despite making my own stories for my characters within them, because having a well constructed, pre-made world at your disposal is so convenient for a DM.
