A former Rally engineer once told me, "Rally did a better job than Atlassian at making engineers think positive thoughts about Jira."
That said, I can't think of a single feature Atlassian released in the past several years that made the experience of using Jira or Confluence substantially better. (I could at least say markdown support if that was ever ported to Jira Data Center.)
The argument for software subscriptions is that it funds continuous improvement, but most of the top complaints from 2011 are just as relevant in 2021.
