e1 or s1?

since aglaea is getting a rerun soon i wanted to ask what would be the best investment for aglaea. im currently running the feixiao bp lc since i lost during her first banner.

considering my build and team what would be the best investment for her and should i change how my build is currently if i get either e1 or s1?
