Super Suite comes with "only" 3 extensions to install:
eCart (to be installed first!!)
Data Bridge and Design Extender are consolidated bundles of extensions:
Data Bridge includes all of the extensions as listed here: extensions.php
Including the new (!!!) Data Assist 3.0 (highly recommended)
Design Extender includes all of the extensions as listed here:
Both Design Extender and Data Bridge have a much better integration than the single extensions and provide a much more efficient work flow.
Despite the fact, that there are still some glitches, WA has hit the nail with these sets of extensions, and to me they are worth every cent of the upgrade fee!
In your case, as you are going to buy the Super Suite, that's of course the price for the whole bundle...
Please keep in mind, that prior to installing any of these new sets, all old WA extensions have to be uninstalled.
However it's best practice to simply rename (and later delete) your actual configuration folder and than (re)install all extensions (including 3rd party) from scratch.
Once there's a new dot-release, installation goes much faster, as you would only uninstall p.e. Data Bridge 1.04 and then install Data Bridge 1.05.
As mentioned before, eCart must be installed first.
P.S.: As you posted your question in the "Bing Search Toolkit"-Forum, this thread might be interesting for you, as Bing Search isn't included in Design Extender/SuperSuite anymore:
