Ceruledge or H-Typhlosion?

I'm currently writing a fic with a plot that would take to long to explain in a post not relevant to it so Just know the main character is a ghost type specialist in Kalos with nine pokemon each based around 9 deadly sins (Wrath, pride, sloth, gluttony, Envy, greed, lust, Despair and Apathy)

I'm currently wondering, What would be more unique to write about ceruledge or Hisuian typhlosion?

I've gone over the pros and cons of both and both are pretty even in my head atleast can't really make up my mind.

So what pokemon would be more unique to see in a fic?
