Having you checked out KendoUI? They seem to be somewhere between the ExtJS/AngularJS spectrum. I've used Sencha's frameworks on 3 different projects now, and I still hate it. For many different reasons: 1. The learning curve: This is probably something you already know. But you may not be aware of is the other effects this can cause. If your team consists of members of different level of experience (from 0+), the code quality is going to suffer a lot from the lack of knowledge. 2. ExtJS and Sencha Touch are 2 different products. Today's web app demands to be runnable on many different platforms. With ExtJS you get point and click. With Sencha Touch you get swipe and pinch. But what if you're running it on a touch laptop that needs both point and click and swipe and pinch? I'm working on a product right now that integrated the 2. While we succeeded at reaching the goal, the result is not something I'm proud of. 3. Sencha is a walled garden that makes it hard to integrate other libraries into it. For the most part, Sencha already have a lot of things that you needed (like data grid, combo box, etc). But what if you want to do complex data visualization with d3? Complex interactive behavior with Rxjs? Or realtime updates with socket.io? Eventually, I found out that no matter which framework you choose to use, you'll end up needing to read its source code to understand what's underneath. If you have to do so anyway, why not pick a framework that's simple to understand?
