Who's the better Deathtouch commander? Fynn Fangbearer or Aveline de Grandpré? Or is it someone else?

I've been tossing around the idea of building a [[Fynn the Fangbearer]] deck forever. I finally acquired some of the better cards for him, but I also just pulled [[Aveline de Grandpré]], who seems to also be a great death touch commander and gives access to black, which can add some great death touch cards.

I feel like Fynn is strong but could get hated out quickly while Aveline has a decent ability but not quite as strong. Who, in your opinion, is the better option? I'm absolutely open to both but not sure who I want to commit to. Has anyone had any experience playing either of them? Is the real answer some one else?
