I haven't really used anything but Iconoclast for the last 10 years. IMO they provide more coverage and protection. I become a fan when I went to IBRA finals in 2010. I had always used PC prior. A few days in started to see some swelling in my geldings on ankle. I bought my first pair of Iconocalasts there. Between those boots and icing the leg I believe it prevented it from developing into something worse.

I did try Pegasus and absolutely hated them. Did try CE and thought they were ok just not as good as Iconoclast.
