The Ogre is basically a Spitter on some seriously good steroids. When I had an all explosive Axton build with the Legendary Ranger COM it would melt just about everything in front of me with all the on kill skills activated, slagged or no, very quickly. However it is really easy to run out of ammunition if you are not careful with the Ogre and it has the same unique fire rate/reload speed quark that all Spitter assault rifles have.
The Swordplosion is a fantastic weapon but has some risk involved since the “projectiles” can harm you if you are standing close to where they land. It also requires the vertical grip accessory to make it worthwhile as much like the Orphan Maker the extra two pellets make for a massive increase in damage.
The DPUH is a good weapon if you take a knee or just want to hose down enemies without much effort. While it does have a sweet spot it is no where near as punishing as the Flakker if you do not try to get into the proper range; it hurts from every angle but hurts more in the sweet spot.
