Choose Hilton's if
Two decades of running the same service is a real signal, and Hilton's pairs that tenure with altimetry, surface currents, up to 12 SST shots a day per region, and a mobile app for laptop, iPhone, or iPad with waypoints and home ports built in.
Choose Chlorofishy if
Both of us offer monthly billing, so that alone isn't the difference. Ours is cheaper at every tier we could compare ($9/month for one region versus their $74.99, and $89/year worldwide versus their $200/year for one region plus $30 per additional region), covers all 38 regions under one plan instead of paying per region, and shows the named raw satellite pass behind every reading. We don't offer altimetry, currents, or a mobile app.
