Also, the upcut bits will pull the wood toward the router (and out of
the blind hole) when cutting a mortise. Having the wood pulled toward
the router base also helps with control of the stock.

Smoother cut, because they slice diagonally.

They cost more, and they may be harder to find.

Could be, but not necessarily.

Depends on what you mean by "best". :-) If you're looking for high quality,
never mind the cost, go for Whiteside bits, available at various places. If
"best" means "best value", it's hard to go wrong buying from Lee Valley.
Woodcraft's house brand is decent quality, too, at an affordable price.

There's also upcut and downcut spirals. Upcut pull the
wood in the direction of the router, downcut do the
opposite. Pick whichever one gives less chipout on
a show face.
I've also seen double-cut types, which are downcut halfway
and then switch to upcut.

Before you do, look at 2 flute, aluminum cutting carbide end mills. They are
made for milling aluminum in a milling machine. Identical to spiral router
bits. Generally of higher quality and lower price.

I have a 1/4" bit I use in a router table for cutting dadoes for plywood and
the like.
Usually works pretty well as it removes the chips as you go, where as a
straight bit usually
leaves a slot full of dust and chips behind.
One word of caution though.... hold on to your work piece, firmly.
Mine has a tendency to pull the work piece through and sometimes away from
the fence,
generating less than desireable results.
There's also an 'up cut' and a 'down cut' version of the spiral bits.

Not the ones I'm familiar with. They're not made for wood, but for stouter
material which removes in smaller pieces.
Sort of like a hacksaw, which will certainly cut wood, but it's no match for
a Ryoba.
