Pros

Cons
Con Commercial license
It's not free for commercial applications.
Con Not very popular
Not really a reason to not recommend it. But it has still a small user base. It deserves a lot more attention.
Con Not modular
The library is not modular (except for some additional more complex widgets). If you only need a few widgets, you still need to include the entire library.
Con Expense: Free LGPL version but expensive to leverage the real power of the framework
The Developer version starts at $745 / Developer
Con Difficult to integrate with other frameworks like React, Vue, Angular...
SmartClient has it's own layout mechanism and doesn't have anything like Kendo UI's framework support for Angular, React, Vue, ..
