it may depend on what type of stock you are useing. Oak and maple are
real hard on bits unless you can afford some real nice ones. (Which I
cannot) I just build some pine cabinets and used a router with no
problem. If I had made hardwwod doors, I would have used a jig, and
had an excuse to have my dedicated hardwood sawblade sharpened.
My 2 cents as well.
