The Herta or Aglaea?

Hello everyone, I would like some help with choosing what character to pull for and building teams.

I stopped playing hsr for a while but came back after seeing the new characters and wanted to pull for them.

I have a firefly team which i use most of the time, but i would like to swap huohuo with lingsha, as ive heard shes better in the team, so i want to pull for her too.

Im looking for another dps to clear higher difficulty levels and dont have many jades, so I would like to get some opinions on which character to get.

These are the 5 star characters I have:

Huohuo, FF, Robin, Sunday, Fu xuan, Ruan Mei, Bronya, Himeko, Welt, Clara.

I have most of the 4 star characters.

Please leave some suggestions! Thank you
