Note that ImageMagick isn't always the best tool, since ImageMagick always reconverts the image, often with lower quality. Often it's useful to have the image to go in as is, or use a loseless resizing. I use img2pdf for that with great results.
I almost can't tell if you are being sarcastic or not!
It's gotta on some level be at least apples/oranges right? You describe a process with more steps, that involves launching a GUI app to do one thing. Maybe its more intuitive, but I would argue the interface makes the user, not the other way around.
