1) The WL software has diagnostics and configuration capabilities for Davis ISS equipment that other softwares do not have. So it is a good tool to have around when you have problems even though may not need it now.
2) The WL software has a very compact database so if you use it to record and store your weather data, you won't use up much HD space.
3) The WL graphical interface has a very, very retro look (some might say hopelessly outdated
); however, it doesn't require a a great deal of your computer resources to run. So it can be run on very old machines you might have laying around.
4) If you are into gardening/lawn maintenance, there is an ag/turf module you can buy that will help you with those. No other wx software has those capabilities.
5) Once you have some historical data, the WL software has graphing options that allow you to overlay data from previous days, months, and years for comparison purposes. Overlays produce some very interesting revelations about your weather. Some people with other software have commented on the WL overlay capabilities as though they didn't have that capability in other software.
6) Some people like the web site graphics that the WL software can produce. It's personal tastes.
