Druid lvl 60 Specs

So as far as i see there are a lot of Druid specs at lvl 60. The 2 i am interested the most in are the HOTW/NS spec and the Moonglow/Resto spec. My question is now, which one is more suited to my plan on playing PvP with my Friends, but still be able to go in Dunegons and Raids from time to time? Will the HOTW/NS give me enough healing for Raids/Dunegons and is the Moonglow/resto spec good in PvP?
