Here's my Davis VP2 mantra:
Wired: Cheaper to buy, harder to install, easier to maintain, no ability for extra sensors
Wireless: More expensive, easier to install, harder to maintain, can add extra sensors.
Keep in mind that the wired distance limit from the ISS to the console is, for most purposes, limited to the labor and expense you want to put into laying cable. In theory, the protocol Davis uses for that connection will go 4000'. I have at least 150' of cable between my ISS and console, and then another wired console elsewhere in the house another 100' daisy-chained off of the first console.
