I'm still researching this myself, but so far, the big thing, at least for me, that Telerik has that EF doesn't is the runtime mapping capabilities. Being able to define mappings at runtime is a big deal to the project I'm working on.
ex. At compile time, I know the general database schema so I code for that. But customers can add custom columns to tables. Being able to access those custom columns at runtime in a more or less native way is super SUPER handy.
