Is there is any best alternative software for motion graphic video presentation rather than Adobe After Effects cc?

Well its depends on what kind of presentation you about to make. For example if you need only a video presentation adobe aftereffects is a good also adobe premier. If there is a slides and pages with next or back buttons;then Microsoft PowerPoint will do the job. If you need mor interactive contents then HTML or even adobe falsh is the best solution.

The Adobe After Effects Sisi is the best because it is comprehensive and can shoot the effects in a variety of high resolution It's more than just a compilation that lets add your own effects

Yes, you can use Animation cc.. also power point 2013 and above is great for simple presentations and animations and can export mp4 from it too,
