Haven't tried those, but do use Stub length drills quite often and try to avoid the cheap import brands as they flex and break all the time, but the better stubs are pretty good.

In the vertical machining center I rarely center drill holes unless the position tolerance is tight, but the lathe you always seem to have a little nub point left in the middle which is the main cause for drills wandering in the lathe and the center drill cleans that off easily.
