Which Turn Do YOu Think Will Be Better CM Punk's Heel Turn Or Edge's Face Turn?

Wondering? I Think Punk's Heel Turn Cause He Was A Great Heel In His Indy Days. And For Some Reason His Character Suits Him Better As A Heel. But I Think Edge's Face Turn Will Be Good? But I Don't Want Him To Become Those Clean Faces. Let Him Be Like Taker Type Of Face, Doesn't Give A Damn About Anybody? Thoughts?
