Team Suite or Professional?

Would anyone be able to tell me what makes Team Suite any better than having Professional plus another free unit testing model.
I have had a look at the comparitive table, but I'm only fairly new to this and to be honest I ended up not knowing anymore after reading it.
So if someone could tell me in practical terms why paying all that money for Team Suite over Professional is a good idea it would be appriciated.

There's quite a bit of difference in the two products you are comparing. Take a look at the link below:

It's the difference between a development tool and an enterprise development suite.

The integration with Team Foundation Server and Team Build is a big plus. A 3rd party testing tool will not report test results to your Team Projects database (or at least there's not a tool available that does, to the best of my knowledge). This applies to code analysis as well (FxCop).

Later on, reports will include Test Results data that was reported to Team Foundation server. Allowing you to visualize the progress and health of your project, team member productivity, etc.
