Their design is just fantastic - especially with the latest update which added better Stations support. When it was first released it was wicked snappy and kind of slowed way down for a while and got annoying - agreed.
In the past month or two, though, it's gotten damn responsive (for me at least). Give it another shot if you haven't used it recently.
