Vulkar Wraith Riven Help

[VinDanger]

which one of these would be better overall?

I'm very torn between these because punchthrough would be very nice on the vulkar wraith, but so would magazine capacity and fixing the weapon's rather inconsistent crit chance, however I'm unsure if the -damage to corpus will be too crippling. here are the builds I would use against corpus:

build with the left riven:

build with the right riven:

Take the right Riven mod if you are confident in your ability to get headshots, I believe it can out DPS the right one against corpus if you can consistently land headshots. (I did not factor in math in my assumption)
