I have had both and I prefer Boat US. I have multiple boats and the all in one coverage was the reason I switched from Sea Tow. I hear they now offer the same deal, so it may be a toss up. But the customer service from Boat US has been great, and you can't beat a discount on fuel and dockage at participating marinas. Boat US also lobbies hard for boaters rights.
