Help with tire choice for 2006 Mustang GT

Hey guys, i am in need of new tires again. I currently have the BFG g-Force T/A KDW2 on all fours. I love the tire, but i went to get new ones today and am caught up with a new tire.

Either go with the BFG's again or try Michelin Pilot Sport A/S Plus

Stats for both tires...

Michelin Pilot Sport A/S Plus
Treadwear:500
Traction: AA
Temperature: A

BFG g-Force T/A KDW2
Treadwear: 300
Traction: AA
Temperature: A

The Michelins are coming with a 40,000mile warranty for wear.. You think this is a good idea?

What would you guys do?

The Michelins come out to like $502 installed.. Last set of BFG's i bought, they came out to $487 installed. (Assuming they did not raise prices)
