>Which Framework do you like the most so far?

I have tried Promatrix, Codebook and Drew Speedies. None choosen yet. I have create my own simple framework.

>Which Framework better connect with external accounting software?

I don't think any with excel better than others at such a specific requirement. You would have to experiment.

>Which Framework helps more on timely project developing with tools?

I am sure they all would. One must take into account that you must invest weeks (if not months) learning the framework. It will take a while to get your initial investment back.
