Three months outdated, but should point you in the right direction.
The only rainbow tier list you basically need is...
Dendrobium > everyone else > Helenium
As far as pure TP goes. When Bloom comes out, Baccara will be top tier (and maybe Dendrobium still), while others like Daisy get even better.
