The answers currently provided are attempting to answer the question from a project level perspective, which is typical, rather than from an organizational and maintenance perspective. And also siding with one camp or another, which should be avoided.
The answer to your question depends on your situation. What type of queries or reports are needed or would like to be seen in the project? And to reiterate what the top response is: the tool should not dictate scrum and to go along with that, does the project need to be somewhat flexible?
A take away from real world scenarios that I have experienced with multiple clients, is that they usually start with the basic Microsoft Visual Studio Scrum 1.0 template and then add things to it. ie: queries, reports, work items, dashboards, etc. Which inevitably leads them back to either the Agile or CMMI template with the burn down reports/queries/work items being added. Have seen this multiple times regardless of the size of organization.
It wouldn't matter if the god of scrum came down and created the scrum template for TFS. A more important question is 'What does your process support; how disciplined are personnel to follow process; and can they agree on semantics? If it's a real bother that the names don't match up, the work item types/names can be changed/added/removed, it's still the process driving it all that matters.
One real important aspect of the templates, from a pure TFS perpsective, is that scrum 1.0 work items may be added to the the agile 5.0 work items easier than the other way around. Why? The fields and data entry points already exist in agile where they do not in scrum. Which in turn reduces the amount of time figuring out which fields that exist in the system to reuse without causing conflicts.
Without sounding factious, and I'm trying not too, it's similar to stating that using Microsoft Word is to confusing to people because there's too many features/functions. Most people ignore these features/functions until there is curiosity or need to use them. Otherwise companies should not have the added expense of paying for Microsoft Word licenses and just use WordPad. Curiosity and need is what promotes understanding and knowledge.
