I moved to the Supermatics from a traditional strap binding. I had no real issue with the strap bindings but I was interested to try the benefits of the Supermatic entry system and I was not disappointed.
The performance is as good if not better then my previous traditional bindings. I had considered Burton Step-Ons but Burton boots tend not to fit well for me and I liked the idea that the Supermatics could be used with any boot.
My friend recently bought the Step-Ons and when comparing them on holiday, he felt that the Supermatics looked easier to engage, particularly in powder or on a slope.
I would recommend these bindings.
