As leaders, Ciara has the edge in damage, with the added plus of not requiring 5 elements. However, Lucina can support Light and Dark units with her LS. Lucina offers a DEF conversion, but Ciara adds 100% DEF ignore. Lucina also has HoT, but if you really want sheer damage, Ciara is a better choice.

Also, I know Lucina has a Normal Attack buff, but if I was looking for that, I wouldn't use her. I think any of the other Hit Count buffers are better than Lucina in terms of buffing that bit.
