Lincoln's Repeater or Blackhawk? Backwater Rifle or Sydney's 10mm "Ultra" SMG?

I'm doing a small guns play through and I want to use one weapon per ammo type. I currently have all four of these weapons and I'm not sure which I should choose.

Blackhawk from what I remember is the second most powerful small guns handgun, second only to Callahan's Magnum. As for Backwater or Sydney, I personally prefer Sydney as it as a higher rof and having an automatic is helpful for when i need to fast fire.
