Anemone is awesome!
Other piercers I like:
Daisy: she's innocent in a lewd manner and deals IMBA damage.
Snowdrop: One of the most "normal" girls available, but her debuff helps more than a Defense bonus against the tougher bosses. (A debuff squad is pretty strong overall)
Burning Bush: must-have for trigger-squads.
Mei Plumblossom: Together with Cattleya, she's a must-have on your whale-ship team. A guaranteed solarblast at the start, though I'd advice saving it against the smaller pests and help your squad get through those, instead of using it on the ancient bosses (it deals relatively very little damage against ancients)

Overall, I think all Pierce-rainbows are well-rounded units, so it's more a matter of personal tastes regarding their design and the strategies you use within your squads. If you don't play with a trigger-squad, then Burning Bush suddenly becomes a lot less interesting. If you don't use Solar Blasts, then Mei Plumblossom and Hollyhock become a lot less interesting..
