Cubancigar nailed it- nothing like the smell of burned powder.
To answer the question - I don't think you could claim one powder as the 'best'. Many factors to consider like the gauge, the payload weight, desired velocity, cost, availability ....
Two that cover the 12 gauge target load spectrum pretty well are Red Dot and Green Dot. Or from Hodgdon you could pick CLAYS and International Clays. All very good products when used as directed.
