can integrate with Jira and stash seamless.
can manage artifacts and deployment targets (environment)
can manage the version of each release.
not open sourced.
Does not have a large community to provide plugins like jenkins.
sometime they are slow to fix some bugs.
if you are tired to choose plugins for Jenkins for features that are not buildin. Try Bamboo, it will give you a peace mind.
Build and deploy.
we switch from jenkins to bamboo for it's better integration with stash.
and the agents can be installed on remote network (behind firewall) to do the deployment jobs!!!
