If you want to give a compelling argument about the Macerator, it's simple: it's way easier to get early game. Way, way, way, way easier.
What? The difference is minimal. The macerator takes more metal, and the pulverizer needs a wider variety. It's such a small difference that a any brand spanking new world can make their choice of either after a single caving run. And somebody who searched out villages instead of digging is more likely to have the lower quantity and wider variety for a pulverizer than all that iron for a macerator
Construction costs:
Pulverizer: 5 Iron, 2 Gold, 2 Copper, 3 Redstone plus 1 iron 1 redstone per engine.
Macerator: 9 iron, plus 8 iron, 3 copper, 4 tin for the generator. (And hope you find that rubber tree)
The difference is 2 gold, 4 redstone on one side or 11 iron, 1 copper, 4 tin and rubber on the other. It's possible to be able to build the macerator and not the pulverizer, I guess, but it would take dedicated surface skimming to do it.
The total cost of ownership and management of a macerator is a tiny fraction of the huge hassle that early game buildcraft power management is.
"Power management" for a single pulverizer is a single sterling engine. Just like a macerator is a single generator. The pulverizer wouldn't be full power but _that's_not_necessary_ for Steves First Machines. And you can keep adding sterling engines up to 4 all pointing at different faces, when the pulverizer would be full speed, at zero risk for any explosions, and crushing the macerator in speed tests.
You can even run a macerator off a redstone engine, if you don't intend to stare and watch it - running the redstone while you're off caving for a 2nd run is in fact a free way to get a full energy buffer and a handful of ore processes for free when you're back
Conduits or conductive pipe are both simply unnecessary for "early" game, which is your stated argument. And the bonus dust is at its most valuable at that early stage of the game.[DOUBLEPOST=1361283438][/DOUBLEPOST]
I use Induction smelter for all my ore as it is the absolute best machine for it and it is as fast as the pulv. rich slag is way too good.
At 5% bonus instead of 20%, it's a pretty sad choice actually. Early game, that extra bonus from a pulverizer is going to make more impact and later with automation available, Factorization or GregTech will give you the 3x for every single ore.
