Each user chooses what software is best for them. I, for one, can recommend you Camtasia Studio because of its High Quality export options plus the advantage of timeline editing using powerful yet, simple tools). Then there is Debut Video Capture Software with its simple interface and wizard to help you record exactly what you need. Also, Snagit proves to be rather efficient due to its simplicity in functionality.
As you can see, these suggestions could meet your requirements but the choice is yours to test them and choose the one which will please you most.
