I've just started using Deis at work recently. Dokku looks like it was a small project sponsored by the company behind Deis. I haven't looked much at dokku-alt.
The thing that I really like about Deis is it supports deployments off of docker images in a private repo on top of git push deploys.
One of the things we do is host a REST service backed by data we generate. We can have jenkins automatically build and publish a docker container to our internal repo, then it's two REST calls to Deis to update the docker container that is running. We generate the data in Hadoop through a longish oozie workflow weekly and we can make two REST calls to repoint the REST service to some new database tables.
I also like that each layer or part of Deis can be swapped out. Want to run haproxy for the load balancing layer instead of nginx? Someone probably has a container that can be dropped in instead. Want swap a more advanced scheduler for etcd, you can swap in Mesos, YARN, or even Flynn's scheduler.
