Adhesive-lined heat-shrink ring terminals. The ring will not pull off a stud under vibration the way a spade can, which is why ABYC practice favors them for anything that matters.

Ancor tins the copper all the way through rather than plating the ends. On a build that lives through heat cycles, dust and road salt, that is the difference between a connection you make once and one you chase down in a wash a year later.
