None of those metrics matter at all!
They just satiate your thirst for links. What you should really be looking at is the anchor texts and the backlink profile.
For example, I have an expired domain with 29 backlinks from cnet, few from yahoo, wiki + clean anchors; guess whats the TF and CF? 6 and 23. DA is 11, PA is 23.
Metrics are not the do all end all...you can easily tamper them
