Would a Container or Atomic work better for certain packages for an application?

I know of Red Hat Containers and Atomic, however I'm trying to figure out what would work best for me.

I have a developer that needs to have an RHEL6.4 OS setup with certain packages, so that it will work with an application he works with.

Could I use a container for this? Vs me installing a RHEL6 as an OS and trying to install the packages and dependencies by hand.

I'm not sure what the best way to approach this.
