Indeed, the problem is on code bases or teams with multiple ways of doing the same thing. I define new objects with.

    var foo = Object.create(bar);

You do

    var foo = new Bar();

Amy does

    var foo = Bar();

and Ellen does

    var foo = Bar.create();

For many values of 'better', the advantage is much smaller than the additional burden.

Thus I have no problem with him finding better ways, but his influence and his way of presenting things as the one best solution causes issues, in my experience.
