"Can someone please tell me one good reason why to use spades?"
Many amps don't allow bananas. I used to have Cambridge A3i amp that allows only spades (no hole in the post). Now I have Rowland model 102 that has Cardas clamp style (with one big knob) terminal for spades only. Whole new lineup of Rowland amps might have it.
