I recommend you to get Allanon or Alan since you don't have those 2 yet.

Choose Allanon if:

- You don't have the following units: Priestess Snow Miku, Dizzy, Fina, or any other good Guard Frontier units.

- You don't have a lot of units with his buffs

Choose Alan if:

- You don't have Alza Masta (for his Leader Skill and some of his skillset for hard content)

So yeah between these 2 imo
