Now, stack the atk debuff and heal and you'll find yourself actually surviving about as long as if you used Osiris, or maybe even not needing to survive long, provided you've optimally levelled up your weapon skills.
In that regard you'd also benefit from the weapon skills, which serve as a multiplier, not an addition to your stats... which brings me to my answer to your answer to my recommendation (lol convoluted phrasing but whatevs)...
As I mentioned, weapon skill is a multiplier, so the 300 difference is easily, EASILY overcome with a 13% addition to your atk multiplier at max skill. If that doesn't convince you enough, well just do the maths yourself.
