I disagree with ghost on the ranges, if you have not noticed, the pbp is incredibly hard to dodge at long range and with eras screwed up stacked damage, the odds are you're going to deal 8+ damage, unlike the dsr which is easy to dodge at long range. Snipers can not shoot through thick walls anymore so they are absolutely pointless. Also, the dsr is much better at dealing more damage fast as the PBP sure, deals 16 damage, but its not a guaranteed 16 damage unlike the dsr that's a guaranteed 12 damage. I find the pbp only good for long range and finishing off foes.

If you ask me what gun to get, my awnser is neither. Get a shipkia. Best gun in the 100-125K range in bases
