The Whole Package!!!
If you are able to, evaluate what products are going to be used by each user or user group and optimize how you package your deployments from there. This will help the IT team immensely when a new hire is brought on board so that they are operational right out of the gate instead of waiting for the installs to happen. Also, you want to make sure that the users have access to the updates on a regular basis so that they are in line with the other team members and using the same build of the software.
Pros
After being in the Reseller channel many years ago, the main thing that the AEC Collection Solves is having access to all platforms without a huge overhead. This is pivotal for those clients that execute every aspect of a project but maybe only need a certain software 5% of the time. Clients were more inclined to not utilize certain tools because their frequency of use did not match the cost that was associated. This allows them to confidently access many tools in their toolkit while optimizing overhead costs.
Cons
One of the downsides that I see to the AEC collection is that the Installations are still very large. This poses issues to those that are utilizing a number of the tools in the collection as it put a strain on the hardware requirements. Having more flexibility to virtualize the software and licenses would be beneficial.
