Both are nice intermediate level planes. Neither is good for a beginner. If you are at the beginner level, get a SuperCub.

If you are at the intermediate level, these are decent planes to get. The PZ is a very popular model and the brushless motor corrects one of the biggest problems of the original - being underpowered. However, the plane still does terrible groundcircles when you attempt to take off, so you need to add a tail wheel and increase the size of the wheels to 2". Addign expanding foam to the inside of the fuselage is still an important means of reducing damage in the even of a "rough" landing. The FlyZone plane is nice, but is extremely underpowered. You definitely need to unpgrade it to brushless/LiPo to make it a decent flyer. The Flyzone electronics aren't too good either and should be swapped out.
