Which is better FUE, Manual or ARTAS?

I am the doctor who pioneered FUE between 1996-2002, publishing the first journal article on the subject in 2002 as a result of 6 years of experimental work with many cooperative patients. I am the original inventor of he hair transplant robot holding two US Patents on it. I licensed the robot technology to Restoration Robotics, who made the ARTAS and we eventually purchased one, using it for a few years, eventually selling it. We found that the manual systems that were developed after the commercial robot were fully developed allowed us to perform FUE faster and more accurate than the ARTAS.  Speed was important.  Also, we found that the transection rate was higher with the ARTAS than with the good manual systems so we focused on the best of the manual system. We purchase every manual system available to compare one to the other and eventually found that some worked better in some situations and others in other situations. Having many types of manual systems allows us to always use the best system for our patients.
