Is fotona skywalker better than picolo laser?

I have a StarWalker and had used Pico before. 
With StarWalker you get the best of 2 worlds, the power of picosecond pulses traveling together in a nanosecond pulse. So is like a train of high peak power super fast pulses, traveling all together arriving at the same time (counted in nanosecond), in fact almost 5 peak of pico in 1 of those nanosecond pulse.
Both benefits, one single treatment, one single equipment, safe, efficient and less expensive than the pico.
As the StarWalker can be fractional ablative, can help reduce also the number of session for example tattoos removal. Another advantage of this. 
I will highly recommend this equipment. But remember is not the laser or the pulse duration y the needy choose for each treatment on the right hands. So effectiveness depends on the laser expert that will treat you.
