Are you after click based casting (click on frame to heal) or mouseover casting (mouseover frame, press keyboard key)
For click casting:
VuhDo’s still solid.
Clique works with any frames but I would recommend not using it with VuhDo as VD has it’s own click-healing setup.
The default frames these days are pretty solid, ElvUI’s frames are solid - Clique obviously works with both.
Mouseover Healing:
