No, this is not the same. With a LED you already know what current source
you need, it's in the datasheet of the LED. What you do not know is if the
LED is bright enough or not - bright enough for YOUR application for YOUR
eyes... Olin keeps telling you this, but you do not seems to understand: See
how the LED is working for you - different LEDs, different current sources,
different frequencies / duty cycles.

With a resistor you may can have experience of capacitivness and
inductiveness of that resistor for example. Or measure the resistance with
high frequency - you'll be surprised...
