Well, that's the classic argument for yak shaving. Most if not all of the frameworks you analyzed will be more than adequate for the app you're going to build. What it should come down to is what you're comfortable with. Focus on the product you want to build, not the tools you are using to build the product.
I think I got the Yak shaving part covered with the first sentence of the post :)
I'm well aware of the ups and downs of exposing myself to choice like this but I really want to get myself exposed to some real world practice with some of the top contenders here to make a more objective choice and I also feel that 'what you're comfortable with' is getting too close to unsupported that I should widen my view.
Fortunately this is not a commercial undertaking, nor am I on a tight deadline so I can afford the luxury of thinking this over. If it were for a customer and it would be required tomorrow morning then the story would be wholly different.
