Which software is better among CATIA, SOLIDWORKS & PRO-E?

Solidworks Is3D design Software which doesn't have CAM, you have to Install3rd party software(like-SolidCAM) to perform CAM. Again Solidworks doesn't have ergonomics study it require3rd party Software (like-Jackhammer, CATIA-HUman module,3Dhuman, NX-Humanmodeling, etc to perform ergonomics study.

Choosing between SW and Pro-E is difficult, they are practically the same however for a beginner SW is preferable since it has a user friendly interface.
