I've had the mirena I've had both! The mirena twice which I found much better.
The copper is hormone free the copper metal itself kills the sperm before it reaches the egg. Whereas the mirena has a very slow release hormone. If you suffer with long heavy periods this would be the right one for you! I had 7-8 day long heavy periods, extreme monthly pain and mood swings. The copper IUD didnt make any change to this and I actually had it removed and the mirena in its place. Which reduced my monthly cramps to a bit of light back ache and a 2-3 light spotting period. But everyone is different.
