Eridian Vanquisher vs. Brotrap Class Mod

All that I use with my Claptrap build is the Brotrap class mods. As you may know, they can offer decent health regen for your team, and a TON of health for yourself. But I also like the Legendary Vanquisher class mods that you get for the sentinel. They offer little health but also TONS of extra skill points. My brotrap class mod gives me 17500 extra health and 32.1 extra regeneration. But my legendary vanquisher mod gives me +5/6 death machine skill. With 11 skill points into that skill, i get +44% extra damage and more. Which one do I use? Explain your reasons. 17500 health vs. Tons of extra damage, health, regen, melee, (etc.).
