Boothill E1 or S1?

Fellow bootlickers of the jury I need help. Literally just and hour ago or so I got a five star in the event banner and lost 50/50, so now I can save considerably less to garuntee my boothill. If I do have extra, would his lightcone or his first eidolon be a better choice? I have every 4 star hunt lightcone fairly high superimposition, but only the herta 5 star. I also don’t have Ryan mei, if that tips the scale at all.
