If your plan is to enhance one or the other as your perma-bard or whatever, Ramza might be the better call. The practical utility of his breaks, where applicable, dwarf anything Lunera is going to bring to a trial unless you're organizing your entire team around Aureole Ray chains - or 7* Loren/Lunera chains, which I am going to term L'oreole Ray since they both have long, flowing hair.
