Yes , Dave, as a "virtual welder" ,without instructor, I overthink before going real

that helps in the end to analyse my mistakes better, I think
the shape of the heat is supposedly different. More sharp in straight polarity. It may be better then for thinner metal as it is more difficult to burn thru .
DCEN is used here very often for root pass to have a neater job more easily no enlarged key hole etc
I try to find reasons when there are contradictions (some manual state that the dcen is deeper, but with no mention of electrode size and polarite this is worthless)
So it helps but then may be there is something relative to the size of the electrode that make some transfer mode more efficient.
I clearly did see dcep refusing to weld , sliding on the surface of the metal even on a precedent bead .
It may be well more quality vs deepness but the heat shape is still sharper. Regards
