In my judgement, you're not a real cabinetmaker until you can execute this joint (and several others) quickly and cleanly. When you can demonstrate hand cut dovetails, no one can say you're not a cabinetmaker. At my job (high-end house joiner) I keep a beautiful hand dovetailed wooden toolbox, with several small trays and dividers. Every time someone asks me can I make so & so (they know me only as a carpenter) I simply ask them to look at my toolbox. Question answered every time.
As for the router method, this produces very strong and handsome (to the untrained eye) joints, and is very easy to do. I used the Keller through jig; it's excellent, but will only cut through joints. If a joint has to be half-blind, I say hand cut it. More expensive jigs will produce all manner of half-blind joints. A snotty woodworker like me will derogate these machine-made joints because of the regularity of the spacing (improper spacing to my eye) and the fact that the neck of the pins is so fat. No router bit can cut the skinny slots between the tails for the pointed pin that I like so well.
I'd like to offer you encouragement to continue, and to do the drawers dovetailed whether you choose machine or hand-cut. You've done the bench, now do the drawers right. There is absolutely nothing wrong with the lock mitre joint suggested in this section, but we're looking for more than straight utility here. (by the way, did I forget to recommend that you NOT put drawers under your workbench?). The dovetail joint will be confusing to you when you begin and you will probably experience a few abortive attempts before you can get the jig to produce the results you want. It would be more so for the hand-cut version. Before you learn to hand cut, you simply will not understand the joint in a gut way. While you're learning, you will make numerous mistakes, and should expect frustration. After you've done it a good bit, it'll be simple and clear, and you'll be able to execute a joint that makes women take off their clothes for you.
I and I suspect others would be glad to guide you further onto the perilous path. "if only you'd taken the blue pill"
