Siemens PLM TeamCenter has been my favorite product after using it for the last 10 years. It has many excellent features such as managing documents, parts, and designs. Regarding integration, I generally prefer to use OOTB integration, and Siemens PLM TeamCenter provides numerous OOTB integrations with CAD applications and SAP tools, making it a comprehensive end-to-end product. They have the TeamCenter Visualization tool, which is a separate tool with strong integration capabilities to help with markup and reviewing design models. The TC viewer is also an excellent product as a separate module of Siemens PLM TeamCenter.
