I was just asked the question - which one to get MSDN or TechNet subscription?
Both MSDN and TechNet subscriptions include Microsoft software that is licensed per user. MSDN Premium and TechNet Plus contain roughly the same software titles, though TechNet Plus does not include any Visual Studio or Expression products.
TechNet Plus subscriptions also include eLearning and other resources for IT Professionals.
Both MSDN and TechNet Plus include Managed Newsgroups, Online Concierge, and Technical Support Incidents (2 incidents for TechNet Plus, MSDN Operating Systems, and MSDN Professional; 4 incidents for MSDN Premium).
The software provided with an MSDN Subscription is for design, development, testing, and demonstration of applications in a non-production environment.
The software provided with TechNet Plus subscriptions is for evaluation purposes only,
