Fractional Laser Vs Laser Genesis Which is Better?

I had ultherapy 5/20/13, lower face and neck,then on 5/28/13 has laser Genesis plus small amt. of Juverderm for corners of mouth due to a drooling down of mouth. Really not much difference is seen. My best friend does the fractional laser and her skin looks great. We are both same age 57, just wondered which laser gets better results, Fractional or Genesis? Also will the ultherapy still work if I had the Genesis done 8 days post ultherapy? Thank You
