no doubt CNC is better than any 3D printing I've seen. Its the first time I've been happy with the results. Ultimately its the process used to make every plastic part you've ever had, it just down to the machines to eek out that finish. For sure its a declining industry that's why prices have come down to almost hobby level in 10years (or less) 3D printing might catch up in quality and price.
The down side for me is time and breaking down parts. Its slow to write cutting code, slow to cut parts and you have to break most parts down to give the machine access to under cuts and end faces. Start up costs are high, I'm just about to order some custom long reach bits to make my life easier.
However once the fix costs are paid off every model will just cost time and modelling board. From the machine 90% of the part is finished state just removing the spru and some tidy up in places that were quicker to do by hand.
I want to get a better cad CNC program the free one with Roland MDW40A works but lacks features like being able to revise the 3D model if you hit a problem and smarter/faster tool paths. My next production step would be to buy a desktop plastic injection mould machine. Machine the injection moulds half's and do away will resin/rtv. Theres a few on the market for around £2000 but I've keeping one hard rule (which keeps the wife at bay) that's never over extend the hobby had to pay for its self so first I have to pay down the mdx40a and then I'll look for a small injection mould machine.
