I know this has been debated several times but would like to know which would be better looking at 3.3 five man dungeons.

My set up is Pally Tank 3 ele shammies DPS and a healer I have a 80 priest or resto shammy.

Shammy has 1 extra elemental every 10 min 1 healing stream totem (all other totems are given by others)

Priest is superior AOE healing ( H-TOC) BK comes to mind Fort and Spirit buff (although I can make Runescrolls so really an extra 50 Stam and spirit spirit buff)

Basically which healer would you use.
