Is Google the best maker sketchup to build my architecture draft ?

Hi guys !
I heard that the maker sketchup of Google is the tool to use when you want to make sketches of buildings.
However, I have recently read that this same Software is frequently used for creating 3D buildings for Google Earth, is this true ?
May you guide me understand the utility of such a Soft ? and tell me if I should use it in Architecture field ?
Thank you.
