Pretty much wut Drop said

For me, Chocolate Cosmos - waifu and chocolate nodes

Lavender - strongest loli in my army

Peach - strongest 5* (big boobs) in my army w/o ampy

Cymbidium is worth it if you have her, her 2x skill 1st turn is beastly but her base stats are lacking, also Megane Waifu!

The following is a personal recommendation, of course, there are other good girls.

The evil ninja Loli is one of them.：p

Cymbidium for me too. This girl is just one on the best golds if not THE best gold. Her 2x skill for everyone turn 1 is unique and even rainbows don't have a such skill activation ability.

OMG can't believe I forgot about HyperLoli, she would be so good with 2nd affection since you can give her 4 def boosting items and she's a counter girl.

One of the best counter will be Mountain Lily. She gain counter with bloomed form + her 20% DEF + 4 equip slot. She can deal over 10k counter damage. Hyperloli is good too right now but less good when blooming will come.

I think she still as good as ever, with beastly active skill that surpass any hit all gacha 5 star girls. (2x on 3 vs 1.7x on 3, activation rate is 34% vs 32% at lv.5) Good boost in raid boss battle and ability to counter. Although 2x def counter is not really high since her def is average at most. But with 4 equipments it is more than enough.

So Hyperloli can be treat as counter or damaging unit depends on equipments. Very versatile and exceptionally good for event girl.

Actually x2 Def Counter with 4+personnal equipements is better than x3 Def Counter with 1+personnal equipements since the Def given by the equipement count in the x2 or x3 calculation. If I look mine on DMM for example, at lvl80 she has 2970 Def (max ampie def, 100% normal affection) + 3245 with equipements. With her +20% def, she deals around 13600 counter damage. It's more than my Kerria's base normal damages.
Hyperloli is good too, but a bit less good I think. Her boss damage is not that good since a lot of 5* have the same thing for every battles and not only raid bosses ones. (and I'm not saying that because I prefer Mountain Lily since I prefer Hyperloli actually).

But I guess they are both really good event girls.
