I agree with Davids comment that their are many choices of Braid to choose from but at the end of the day the difference between them is not night and day. This is even more true when it comes to using braid on a baitcasting reel. Day in day out original Power Pro is a excellent choice.
When considering braid for a spinning reel is when I have notice the characteristics of braid to come more into play. This especially true when the choice goes to braids with extra small diameter such as Seaguars Smackdown and the extra casting difference gained . However this extra benefit comes at a price. Great line but its not cheap.
