Simple, people have different opinions because people drive their crossfires differently. If you don't do hard cornering or spin your tires very often the cheaper tires will last you longer. Also the tires will perform differently on the limited vs the SRT. That extra power the Supercharger gives you is enough to melt those rear tires quickly. Another factor is location. If you live in a cooler climate the tires will stay cooler longer. This was my issue with the Hankook tires. For me they heated up way too quickly, when I went on spirited runs, causing me to slide all over the place. In normal everyday driving they were okay. The DSW's were also good normal driving tires, but I never felt comfortable on them when driving quickly. They just felt too hard and lacking in grip in all corners. The Michelins Pilot Sport A/S treated me very well, but I wear them out very quickly. If I skipped two dragon events I could probably get 3x the life out of them. Okay maybe not 3x but darn near it. This winter/spring I hope to pick up a new set of wheels to put summer rubber on. At that point I think I'll be able to keep the Michelin PS3's going for close to 25 - 30k miles. Finally this is my opinion of the 5 different tires, and we all know about opinions
