Vivica or Neith, Guinevere is already maxed

I don’t have a yellow team healer. I can max either Neith or Vivica. If I use two yellows together, my option is Guinevere which is maxed and Neith maxed or Vivica maxed and Neith T3 70… Darts are hard to come by so this choice is difficult. Any suggestions appreciated.

Vivica would be my choice… 5* healers are great.

Viv easily, getting experience with slow heroes is huge as some of the game changing heroes are slow and especially her costumed counterpart will service you in more places than neith.

I would suggest Vivica as a better choice.
