Which is better? DH or DB?

Subsuba - Lost City

Well, since DH (Dual hammers) have lower dex requirements, and higher strength requirements than a dual blade, so does that mean I will miss more (no accuracy gems added or anything) with a dual hammer than a dual blade (as it has got a higher dex but lower str requirement). And if so, how much more would I miss? And which weapon is better?
