The Makerbot 2 does look very nice and I like the high resolution and larger build area - but I'm holding out for one with dual extruders.
As for head drift and maintenance, no head drift and almost no maintenance required. I had to level the bed as it wasn't quite right when I got it (UPS clearly smashed the package as always, though, so it was probably right when it was shipped).
I think the manufactured steel-frame approach that Solidoodle and MakerBot have taken is superior in many ways to the cobbled-together threaded rods/hardware approach that RepRap designs take - you pay more for a large build area, but it's easier to get decent strength and much less fiddly in terms of setup (no adjusting bolts to make rods line up and the like). Sure, you can't make a copy with just a hardware store and a 3D printer, but for the price and functionality difference, I'll deal with that drawback.
I've printed a couple of decently complex models and what I've found is that settings and filament matter a -lot- more than anything else. The print head goes where I want it to and the extruder pushes the amount of plastic I request through the nozzle - beyond that, it's all about making sure the filament isn't expanding too much in the hot end via high quality filament and making sure there is -no- water in it, and getting the slicer to request the correct amount of plastic at the right rate.
EDIT: I originally said .3 vs .2 - but it is actually .3 vs .1 - so the R2 is much more fine. Still - $500 is a good price for this at all.
Can they both use the same filament?
If you get the heated bed option, yes.
Check out RichRap trying out different "resolutions" (layer heights) on his MendelMax printer with a Wade's extruder here to learn more about how layer heights work:
