Many factors affect this choice. The major factor is the construction and decoration of the premises. Can the location be wired and how much labor will be involved in wiring for the alarm? Will wireless devices be able to communicate to the alarm panel? Plaster walls with metal lathe in them can block the wireless signals. Large mirrors, foil wallpaper, metal lockers and other radio systems nearby might prevent a wireless system from working properly.

Many new systems integrate wired devices with wireless devices. The main thing to consider is whether the system meets your current needs and whether it can expand to meet your future needs.
