With laser there is no concern with holding pieces down with a strong vacuum, you can machine smaller pieces without them flying off, you can cut zero radius because there is essentially no tool diameter, you get a glossy finish with acrylic. With a CNC router you can adjust the depth of cut to 0.01mm and use a wide variety of tools for different tasks. With lasers you have to worry about fumes and fire, with CNC you have to worry about dust and mess. Unlike lasers, with CNC you have the cost of tool replacement, sharpening and calibrating. His final comment really makes the most sense. Each machine has weaknesses and strengths, and you need both to have a versatile workshop.
