I would much rather cut dovetails by hand. It takes some time to learn how, but in my opinion, the time spent is well worth it. They take a little longer than a jig, about 2 minutes per dovetail, but I find it to be much more satisfying and less stressful. My reasoning has to do with the whole thing about having to put on ear, eye and lung protection for woodworking, and then having to clean up the fine dust that routers kick up into the air off of everything in the garage ... takes the enjoyment out of it.
That is just me. Sorry if it is not 100% on topic.
