I would pick and choose based on functionality. This post won't be as informative as Petite, since it's difficult for me to go in-depth about healers.
One pure healer (Camilla or Iris), one for versatility (Sedis/Chydis), and one for utility (Fedora or Liana). There are some exceptions because some healers have an amazing skill or additional functionality (AW ability) that makes them more appealing to use.
On the DMM version, I am using Iris (AW45, 18 cost), Liana (CC80, 19 cost), and Sedis (CC44). Despite Liana having better stats overall when compared to Sedis, I still use Sedis very often because of her skill being very good to have. CC44 Sedis is also similar in stats to an AW45 Iris even though their HP and defense stats differ. Despite having a lot of healers (1 dragon shaman and 4 healers), I still use some of them frequently. Echidna (Dragon Shaman) still sees some use because of her having the function of being able to nuke enemies when her skill is active.
I have a Fedora at CC40, but she's at 20 cost so it's hard to find her appealing when I have Liana. Min-cost AW Fedora should still see some use because of her low cost (16). She'll easily replace the need of a min-cost silver healer.
People like using Black Healer Iris because of her skill and AW passive, but I won't be making any comments for her.

I couldn't find the post that had healer tiers.
Anyway, if I had to choose from any of the healers if I had them, then I would pick Saria, Camilla, and Sedis. Saria's skill can allow her to do the work of two healers if two tanks are getting beat down. Camilla for the high healing power if I have a beefy tank (3k HP+), and Sedis just because.
