Mythic+: Farseer or Totemic?

I’m going into mythic+ for this season as a resto shammy (both because it’s super meta and I adore the playstyle) but I’m stuck between either Farseer with the focus on riptide and ancestors (with less mana sink but worse AOE heals) or totemic with the big AOE heals with totems but the major mana sinks. Which one do y’all use for mythic+ progression and higher keys?

It’s simple, look at raider io and see which one is used more in the tops, maybe the answer is totemic
