You need to make the decision on the material you wish to engrave, coupled with the quality and speed of manufacture required.
For example:
Wood - I would use a CO2 laser.
ABS Plastic - I would use a Fiber laser.
Metals - I would use a Fiber Laser
Glass - for cheap products I would use a CO2 laser. For expensive products like high end Perfume Bottles, I would use UV if price was not an issue.
