The SBS-1e may be more sensitive, but I can't see how Kinetic can compete on overall functionality.
Most users who switched from an SBS-1 found the Radarbox more sensitive, so it may be that the SBS-1e has caught up with Radarbox. But the overall Radarbox package is so much better than the SBS-1e, that needs Planeplotter, BSAlert, FD7, and all the other addons to get even close to the Radarbox functionality.
