For comparing the two, the pulverizer beats the macerator at a first glance. Though the macerator has waay more upgrade options. It's like comparing a modern car to an 80s car that slowly turns into a formula 1 car. For those who've used a rotary macerator on 13.5kRPM, you know what I'd talking about. It will blast through a stack of ores in just a few seconds, compared to the 4MJ/t limit of the pulverizer.
If you want to say "But the pulverizer gives extra things too so it's better!", That's what the Industrial Grinder is for. Instead of a set chance, that baby just throws the extras at you in tiny pieces instead. Which overall is better unless you have the luck of a euro millions winner.
