Actually, your conclusion is right. But it's the wrong rule.
A generic member is a member that has itself type parameters, not a method
that has a type parameter as a type of its parameters.

Applicable is the rule of more specific parameter types:

"Otherwise, .... if one method has more specific parameter types, then that
method is better. .....
A type parameter is less specific than a non-type parameter. ...."
