Cerydra E1 or S1?

So with the new banner releases I'm planning on finally picking up Cerydra, since I had to skip her for Evernight last time. HOWEVER now I have enough pulls left to also get her E1 or S1.

I'm not sure what's worth more in my situation atm (for reference I run E2S1 phainon with E0S1 Sunday and E3Bronya and DPT). Also I do have Cyrene but since she is in my Cas team, I can't really use her atm.

So yeah I could really use some advice since he's still one of my favourite characters to play with! ^^ Thanks in advance!!
