I've only used the Jeppesen charts, never tryed the avioportolano ones.
I can tell you that aviportolano gives you more dettails about the place you want to land (if there are resturants, hotel/hostel, ect.), so peraphs is usefull for your trip that you are planning.
However with the web sites that the other italian friends had given you can have more or less the same info.
We have charts printed in Italy as well but are pretty similar to the Jeppesen one.
