Which one is actually worse: C-PTSD or BPD?

Both C-PTSD and BPD mess with your mind in ways that are hard to even explain to people who do not live with them. But I wonder, if someone had to choose, which one is actually more painful, more destructive, more exhausting to live with?

And which one drains life more? Which one is harder to treat or live with long-term? I want to hear from people who have experienced both or have strong views on either.
