The scarf joint seam with random points leaves a really interesting texture that when combined with wood filament could form a VERY convincing wood grain pattern.
orca slicer is really good. Just their library of plug and play calibrations is enough of a reason to download and try. It fixed a problem i had for a few months that I couldn't fine tune with prusa or cura. Accuracy of parts is pretty consistent too. I am able to print abs parts as is without having to calculate shrinkage.
While it might be true that not a lot of people use Orca slicer and it's vanilla form, a whole hell of a lot of people use bamboo slicer which is a derivative of orca slicer.
