Please consider the mechanics and software, a robustly build, well engineered printer with highly developed software will create a better model every time. Stratasys has numerous patents that highly improved to process the other companies can't incorporate. I've found a wide range of differences in a variety of the low end 3D Extrusion builders I've tried. Some do it well others don't. Poor mechanics, design and software contribute to these variables.
I'm looking forward to the continued development of low end 3D printers that aren't extrusion based modelers.

Not to disappoint owners of these $100'000 machines, but for me it's hard to imagine why a $400 RepRap should print parts substantially different.
Strength is a matter of the used plastics and the layer bonding, i.e.
the nozzle/room temperature it was printed with. Texture is mostly a matter of layer thickness. And you can fill any plastics - as long as it's available as filament - into a RepRap and print it at any temperature and layer thickness imaginable.
What you're really asking for is a comparison of different plastics and different printer settings. And this can be set for every print or even every layer individually.
