Tony,

1) It works effortlessly with all of my Android devices. Top Meteo may also work, but it's not transparent.
2) XCSkies allows me to look at 3 different models
3) I find the data easier to consume on XCSkies. That may just be familiarity.
4) It's cheaper. That's not much of a consideration.

The big knock on XCSkies has been support. From what I've read on this forum, Top Meteo is only doing a little better in that regard.

In a world with XCSkies, what advantages do you see in Top Meteo?
