Lilina>lugh.
First, lilina has luck, res, and super fast support with roy. She also gets a free thunder tome. She HAS AN INSANE FREAKING MAGIC GROWTH!!!!! And, I calculated that lugh has a 12.23432% chance of being RNG screwed. On the chapter lugh joins, he starts in this villiage, WAAAY out of the way. Don't bother to recruit him. Lilina>lugh.
