Using SetObjectToPath vs RegisterFunction for assigning C# methods

[BrianOstrander]

Somewhat of an open-ended question, but are there any important performance considerations when choosing between the following ways of assigning C# methods to your lua environment?

Lua lua;
        
void InitializeLua()
{
    lua = new NLua.Lua();
    
    // A
    lua.SetObjectToPath(
        "a",
        (Action)ExampleMethod
    );

    // B
    lua.RegisterFunction(
        "b",
        this,
        GetType()
            .GetMethod(
                nameof(ExampleMethod),
                BindingFlags.NonPublic | BindingFlags.Instance
            )
    );
}

void ExampleMethod()
{
    // Logic
}

I assume they both have their pros and cons, but using method A is more convenient and what I typically lean towards.
