Harold brings up a couple of points that can be addressed. A vertical can still score without a scoring blade. On a Striebig, the riving knife can be adjusted to act as a stop for the blade to make a scoring cut on the upstroke of the saw carriage. Because it is using the same blade, the scoring cut is then same width as the full cut, resulting in no offset.
Regarding the scales, there are two points. One is the vertical axis benefits greatly from a digital readout since the scale is read going down first and the going up for rip cuts. I had one and could not imagine not. Second, on the horizontal axis, for pieces longer than forty inches, I made up a chart to convert metric dimensions to be able to set the stop. I used metric for vertical parts based on 32 mm construction, and imperial for horizontal parts. I had a digital stop on the horizontal axis that went bad and realized it was not necessary to repair.
My issues with a slider is the ability for material to move when cutting, and having to reach out to remove each cut piece, along with the greater potential for kickback.
