You should use what the factory recommends and while you don’t have to change the plugs every 25k miles, in most cases, I would never allow plugs to remain in place for a 100k miles.
Even with platinum plugs subtle misfires may develop long before a 100k miles and allowing the plugs to remain in place that long may cause the plugs to seize in the cylinder head. This means when removed the next time they may strip out or damage the threads and it’s going to cost considerably more to fix this problem.
