Argent Peacemaker or Sentenza?
Silent Nightblade, Avenger, Combuster…you already have all the weapons you need for the entire stratum.
Argent Peacemaker and Sentenza are both useless - the AP is weak against the jellies and the Sentenza is weak against the lumbers and gun puppies. In addition, both of those weapons do comparatively little damage against the monsters they're supposed to be good against. I recommend you stick to your swords and wait for the Antigua updates to come out before you consider using a weapon from that line.
If you absolutely insist on getting a gun for Jelly King runs, get Polaris/Biohazard. Their bullets might not be as fast as the AP/Sentenza's but they're excellent crowd control choices and would complement your swords quite well if you know how to use them.
Currently, both versions are almost useless due to split damage, and are certainly not viable guns for a JK run (all will perform worst than a normal damage weapon there).
You may want the probable upcoming patch which is currently discussed and would change both weapon damage type. If it happens as is, the Sentenza would become a viable shadow weapon and Argent a viable elemental weapon. Without the piercing part, both would be good options for JK runs.
