Not the same. Dani is unique bc she lost her powers in deciMation at a time when over 90% of mutantkind lost their powers and many of them are or will be citizens. Storm doesnt properly represent them as someone that lost her powers by Forge's gun
Magneto lost his powers in M-day but that was very shortlived and barely got to feel what it was like to be a depowered mutant in the world. Compare this to Dani, who lost her powers and remained like that for years. I dont think Magneto nor Storm share her perspective as they are both far removed from what life is like for the Scarlet Witch's victims. Dani didnt have the same privilege that Mags got by reversing it within a matter of weeks.
