ExtJS/Sencha Touch has been the framework of choice where I work. We complain about it a lot, it has a lot of bloat for probably 90% of use cases, a number of bugs, an extremely poor forum community (I'm looking at you, Mitchell Simoens), and you have to pay for it, but...
Well, I was going to say something good about it, but nothing comes to mind. To be fair, we've built some pretty complex applications on it, so clearly it can be made to work. It just doesn't feel natural, and you have to work around a lot of issues.
For some of the mobile development, we evaluated Angular, Knockout, and even briefly Meteor, but there was a desire for pre-canned view components available in the framework instead of writing HTML snippets/templates. It's too bad, because I really liked Angular and Ember (I didn't personally look at Meteor). I'm hoping to be able to use one of these on future projects.
