sound wise - it's a matter of taste.
i have experiences with one of each... i have a DS-1 and it's great for what it is, a straight forward disto and the quality is undeniable. a friend had a Dano Metal distortion, can't remember what it was called... but it broke with moderate use. now it just makes a primal screaming noise... boss might be slightly more expensive but still worth it in the long run.
