I am developing an ASP.Net web api application and using kendoUI for client side. I found out this blog post which describes the differences of KendoUI and Telerik, but it does not reflect any architectural difference between these two. Is there are big difference in these two UI frameworks in terms of there architecture which could result to performance differences? I am curious to know the in depth difference and why Telerik team decided to come up with a new solution as KendoUI.
