Dubble vs Snagit: Which is best for you?

Ability to capture screens of information from the Internet. Although I use it for my travel itineraries, it has also come in handy when I want to document a procedure to follow for some task such as telling someone how to activate/deactivate my house alarm system (I can illustrate with pictures and words)

With the screenshots, you are not able to increase the size of the picture, there is also a lag time when initiating screenshots and video.
