You can also get better finishes w/ a 4 flute, as you are getting more
cuts
per rotation.

Depends on the job at hand. Often you are better off with fewer flutes so
you can eject the chips----nothing is cut and dried when machining with end
mills----each job may have a different requirement. That's why there's such
a large variety of configurations.
