Your test system should reflect your prod system. Why run Debian if you intend to deploy on the latest ubuntu? Unless you want to use VMs. For other stuff that does not alter the system that much, you can find more recent version in the backports.
It has integration with systemd, but moreover, I think the promise of Debian-derivatives is one of "we are boring and old, but also boringly stable". Now, throwing in backports undermines that promise. I think one is better of with a distro that moves faster.
