====Note, numbers fixed 1/6/2013, numbers changes====
Figured I'd get some actual math in here since a lot of seems to be based on opinion or anecdotal evidence.
Number in ()'s for Pulverizer are attached TE Steam Engines. Number in ()'s for the Macerator are over-clocker's installed.
Note, on Macerator(4) and (5) I expect you wouldn't be so crazy as to attach a single generator. You can see some very vivid discrepancies. As far as Ore per Coal, the statement made earlier that you will spend less time on wood collection in the beginning if you user a pulverizer is semi-correct, but only if you use charcoal as a fuel source. Using coal just means more/less time mined, depending.
Out of the box, realistically both engine/machine setups are about equal in resource, however there is a very important point to make here. If you use TE's resource distribution, You will have to spend mining time at both lvl 45 and lvl 11-20 for the TE stuff due to gold, where with a IC2 setup you can pretty much stay at lvl 45, but this may or may not be off-set by rubber-tree searching depending on seed. It's fair to say both are about equal in time on average, but individual results will vary.
As you can see, a pulverizer out of the box with a single engine is 2x faster and and 60% more efficient with resources. At 2 overclockers, your macerator is now .98% faster than a pulverizer, however you offset this with using ~20% more fuel than a default macerator, and nearly double more fuel than a pulverizer.
It appears that essentially, resource speaking, considering cables and upgrades, both setups are going to be essentially equal on resource usage up to a point, since as soon as you get one of these machines the future upgrades take less time. Also, GT is a moot point as TE is going to add in a GT-style choice for the pulverizer.
An important case to note, however, is with a macerator you will not be able to automate it very quickly due to constraints of wooden pipes and redstone engines. TE machines simply need placed next to an inventory, and this allows you to more easily walk away from your machine with a hopper, while you may have to baby the macerator.
However, this is not the whole story. A macerator is useless without an electric furnace. Let's look at the actual combo of a macerator/furnace vs an induction smelter. While some may argue this is not fair, I would argue it is as all three are indeed tier 1 machines.
Now, here we see TE shine. It takes 5 Generators, a 5x overclocked furnace, and a 5x overclocked macerator to get near the speed of an induction smelter with two engines. I am not considering power-wastes at this point, since we can feed both systems exactly the amount of coal needed within the range of internal buffers for all devices. Adding in another set of over-clockers and a third generator wil get you the process 2x faster than an induction furnace, however again I want to bring up that at this point you are using 15 blocks of space (ic2) over three blocks of space (te).
I think it's quite clear here, while you are limited by gathering your fuel source or by space(no clue why space is an issue, but heck, I don't judge), sticking with the TE machines will indeed be a better use of your time and resources, while in an environment where you no longer worry about gathering fuel you can then go with the IC2 machines for the speed upgrades.
And before anyone starts going with the geo-thermal start debate, the magmatic engines in TE are their equal in MJ in almost every way.
Side Note: going forward, don't always assume everyone uses Tin for lava cells. At least all of us on the DW20 pack probably use Aluminum cans for vanilla liquid distribution.
Also, to the speed issue, Since it takes 15 blocks in IC2 to equal three blocks in TE, you could add in three sets of furnaces and it would take much more infrastructure in IC2 to match the speed. So pure speed alone, the IC2 setup wins in the very end, but till then you are almost better off using all TE machines to create that final setup.
edit: Numbers changed as I over-did the over-clockers, numbers are now in line.
