I used to use Marathon on Mesos for deploying Docker containers, and orchestrated it via a hacked together Jenkins cluster, which worked well but took a lot of configuration and was somewhat brittle.

I moved to Kubernetes about 6 months ago and have been really enjoying it. My first production cluster was hand rolled on AWS, where I found the cloud-provider load balancer integrations extremely helpful (https://kubernetes.io/docs/user-guide/load-balancer/).

I'm now using Google Container Engine which is effectively just a hosted Kubernetes cluster on GCP, which has really been 0 effort setup, and have been deploying to it with Wercker (http://www.wercker.com) [Disclaimer: I currently work at Wercker as of the last few months, but was a fan/user for many years before joining]

One thing I noticed across Openshift, Mesos, and Kubernetes: none of them handle the Docker daemon on a node hanging particularly well, which in my experience happens fairly often.
