Depends on what you're looking for, The Peacemaker seems better at a glance, Neither are endgame material though. Even if it is a new server. I'd save your money depending on your current weapon and focus on a good endgame weapon.
I think the peacemaker is a lower level weapon too, Allowing for more leeway with strength equips. Not to mention it's significantly cheaper. If I had to choose between the two, I'd choose the peacemaker definitely.
