It is easy to check reviews and the two cams' specifications
over the internet. Clearly do you mind the wieght of a cam you may
carry, how serious or particular you are with pictures or video
qualities and how well or versatile you can control your photo
outputs versus your budget, the HX1 clearly beats H20 in many ways
as according to specifications. I am not saying that you cannot
take good pictures with the H20 but between the two seems like the
HX1 is above the H20.
