The thing about electrics: You can't just use one a couple times to make a decision. It actually took me face like 3 weeks to get "used" to it. Also, once I got into the habit of using it frequently, that helped a lot.
With a razor, I can skip a day or two, and not look homeless. With an electric, I can only skip one, and by the end of that 2nd day, I'm borderline on work-appropriate appearance. But, with an electric, I would do a quick once over in a matter of a minute every day, and my face stayed smooth, and looked good. Just like shaving with a razor, the shorter the hair you're shaving off, the better shaving feels.
That being said, that was when I was clean shaven.
This is me more recently, but still before I had a method down. It looks much better now.
With a goatee, here's my tool kit:
I shave with a Mach 3 I have an electric trimmer with a depth-adapter for longer facial hair.
Here's the trimmer set I have, but I really only use the trimmer, and the larger adjustable-depth head.
I usually shave with just the Mach 3. If I've had a few days off, and my facial hair is a bit long, I don't try to shave it all off with just the razor. I use my trimmer without the depth adapter. It's basically like a very small hair clipper, and I use it to "knock down" the hair first. Doesn't take more than 20 seconds. Then, I go over it with the Mach 3 with shaving gel and I get a smooth shave without the tugging I'd have gotten if I had just done it over the longer hair.
For my facial hair, I use that same trimmer to shape the sides, then I use the longest setting (9) of the adaptor and "comb" through my facial hair with it. This can take a while as you kinda hafe to work through it in all different directions to get all the hair to feed through the grooves so it all gets trimmed. Then I pull the depth-head back off and trim my mustache free-hand. If I tried to trim my beard with a scissors, there's no way it's be even. It would look like a lawnmower fell on my face.
Sounds more complicated that it really is, but it works well for me.
If I were to go back to being clean shaven, I would go back to electric, but it would be a 3-ring deal, not the bars-across kind.
