idk, plasma leaves a lot of slag and depending on the application requires substantial finishing work. mill is fine but has a limited work area (like this waterjet), and at least in my shop, cutter lifetimes aren't great. Thats probably because i don't have the best processes. Also holding down sheets well enough is a substantial hassle unless you're set up for a particular run. Metal routers are really noisy and are arguably more of a hassle than mills. but I totally agree with your last point, its less convenient, but doing small to medium runs though a local water jet shop is pretty cost effective. Its mildly pricy but they will source standard material for you, and you pick up clean parts a day or two later. even ignoring maintenance - dealing with the up front cost, the consumable cost, and renting enough space to keep the thing is a pretty serious commitment. I have free access to a 4x8 cnc plasma gantry and I still send out quite a bit of work to the water jet place.
