Whats best speed torque KL34-180-90 servo or KL-8070D steper

Hi folks!
I start project the router with 2200x1200x600 for wood 3d work and like know whats kits below offer the best relation speed x torque for my project.
I think in use DC servo with 5:1 reduction or anything alike or direct drive stepper motors, Hiwin linear guides and ball screws.
I contacted Automation Technology Inc. | Stepper Motors, Servo Motors, CNC Stepper Motors, Stepper Drivers, CNC Kits, Stepper Kits Automation Technology Inc and he not have any data about it, i really like know your opinions!!
Thank you

Doug
