A down spiral will have the least tendency to raise wood fibers at the
top of a mortise, but will also tend to pack the chips into the bottom
of the mortise.
Chip-out in a mortise may be a sign of a not-so-sharp (even if
brand-new!) bit. A good, sharp bit should shear wood fibers rather
than breaking them.
If chip removal isn't a problem, then an ordinary (plunge cutting)
straight bit should produce the most consistantly good results.

I am not Pat but I use the TS for the slots and a Mortising router bit for
the tennons. Using a TS is 10 times faster and easier on the equipment for
making panel slots.

LOL... That would totally discount my suggestion.
