I love X-treme x-men and CC but the truth is that during the time NXM was sellng much better. It was the number one comic in sales almost every month. I remember it cuz i was reading wizzard magazine at the time and they had the sale numbers of the first 100 comics if i remember correctly. X-treme sales started strong but fell after some months. Also NXM sold more than 100k copies per month. You can find the actual sales in Comichron
