Depends on the cooldown but I can't see poacher being that great tbh. If I was playing Nunu I would go poacher but if I was playing Yi or Udyr I would go skirmisher for sure. The bonus gold on poacher only applies if you're counter jungling and unless you plan to counter jungle a lot then I can't see upgrading JUST for the cooldown reduction.
Remember new jungle has a wolf scout and river vision now which makes counter jungling riskier as there are more ways to get spotted, so unless you plan to deal with the risks then most likely you're just getting poachers for CDR on smite, which MIGHT be worth, but the other items have some seriously great benefits as well, and I don't see the jungle camp buffs as too critical that you need smite for them all.
