Start with the reason you searched for Downlink
Downlink is known for bringing real-time satellite imagery to the Mac desktop. If that is exactly what you want, the useful comparison is not generic wallpaper quantity; it is satellite source fit, regional views, update behavior, and whether the wallpaper can also carry weather context.
LiveAtlas is an alternative when you want a satellite Earth wallpaper that also emphasizes regional cloud maps, optional local weather overlay, and typhoon information overlays.
When LiveAtlas may be the better fit
Choose LiveAtlas if your main interest is watching real cloud systems across supported regions, keeping a quiet Earth view on the desktop, and using the Mac menu bar to change the satellite wallpaper workflow.
It is especially relevant for searches around live weather wallpaper, Himawari satellite wallpaper, typhoon tracker wallpaper, and real-time cloud map desktop use.
When another app may be enough
If you only need a simple full-disk Earth background and do not care about weather overlays, typhoon context, or regional source pages, a simpler satellite wallpaper app may already cover your use case.
The important point is to compare by the job: real Earth wallpaper, weather-aware wallpaper, or decorative live wallpaper.
