I just saw that we are getting another free 5 star selector and I'm very indecisive on who to pick. I'm stuck between e3 Ruan Mei and e1 Topaz.
So here's the situation: Ruan Mei is one of my favorite characters in game. I have her e2s1. I play her in The Herta teams, DoT teams, break teams and sometimes with hyperxarry Anaxa and Phainon. On the other hand, her e3 isn't super useful since it's just a level upgrade, but I'd be one step closer to e6.
As for Topaz, I have her e0s1. I stopped playing her as soon as Feixiao teams got powercrept. Her e1 seems good but I don't know if I'd be getting much value from it, since follow-up teams are in a pretty bad place rn.
The 3rd option would be to save the Golden Companion Spirit for the next free character event but I don't think I'm patient enough for that haha.
Any advice would be appreciated!! 
EDIT: Thanks for the advice! I'll be keeping the Golden Companion spirit and waiting for a better unit to be added to the shop.
