Hi all,
I was after some community input on one simple, but big decision on my next 3d printer build. I am designing a 3d printer that I plan on being very good, as in using more metal parts for a more rigid build and using SC10UU bolted to carriages RATHER than LM8UU bearings zip tied to printed carriages. I am copying many aspects of the Stratasys uPrint SE Plus printer. (I have one in my workplace, so I have access to extensively study its structural design.)
XY Axis at the top of the frame, Z axis moves down (same as ultimaker makerbot etc)
The decision I am currently having trouble to come to a conclusion is how the Y axis will be driven.
In the makerbot and ultimaker the Y axis is driven by a nema 17, with a closed belt, driving the rotation of a long smooth rod which has two more pulleys on it driving both sides of the Y axis.
Examples:
In the background of this image: [thingiverse-production.s3.amazonaws.com]
A better example: [ultimaker.ipbhost.com]
So, this seems to be the more common way these printers have their axis driven, but is it the better way?
The alternative being having a Nema on each side of the axis, (like is done for Z in prusa i3)
Can be seen in both these videos:

[www.youtube.com]
So, If you ignore the extra cost of a second Nema and ignore the more tedious wiring job of a second motor, which would have more precision, because my end goal is a EXCELLENT performing self designed printer, not something that is nesacarily cost effective.
Always appreciate your input, sorry for the bad explaining of each type of axis drive but bad explanation is just me
Thanks for viewing.

Depending of the design you'll choose, you can go for supported linear rails, like SBR10, or much better, Hiwin miniature MG series (or into other brands SFK, NSK, INA, Bosch...). The quality of miniature linear rails is that good that you can drive a 3D axis with a single rail and carriage. That would be my choice for a high quality printer.
