What's easier to level?

I'll have to go with the jump start Dual Blade as a quicker way to level; a pre-Chaos created Dual Blade will be slightly weaker since they'll lack mastery books, which will noticeably slow down the exp/hour. The HP loss doesn't seem like a big deal unless you're at level 100+ spots (hypothetically). Level 80+ mobs shouldn't deal more than 600 or so damage. So. . . . the choice is clear.
