Answer : There isn't a single, definitive answer to this question. SketchUp is a very versatile program that can be used for everything from designing buildings and furniture to creating illustrations and animations. It's also easy to learn and use, making it a popular choice for beginners.
On the downside, SketchUp is not as powerful as some other 3D modeling programs, and it can be somewhat buggy. Additionally, because it's so popular, there are a lot of third-party plugins and extensions available for it, some of which are quite good but others of which are not so great. So before you make your purchase, be sure to do your research to find out which plugins and extensions are worth using.
