Shouts x Meditations - Guardian DPS
Meditation for fast and instant heal (more like your skill 6) and AH heals you better in the long run, especially with team mates. If you are going for PvE (mainly solo)I’d suggest meditation and if you going for any type of dungeon, WvW or sPvP then use AH.
Also Meditation offers a wider choice in stats relatively, in comparison to the standard Toughness, precision for AH based builds
