Haven't personally used Taiga, so can anyone comment on their impressions, maybe also compared to something like Redmine or Jira? What's good? What's annoying? What's missing?
Once experienced people joined the team we switched to jira.
What was the benefit and the positive outcome from doing so, outside of familiarity with Jira?
Conversely, what was problematic about the idea of sticking with Taiga or another solution, what would you miss out on?
I think that every software has some shortcomings, like some people swear by Jira, others hate it, personally I can see both sides: it works, but at the same time the REST API has stuff like createmeta which you need to use for getting issue field types programmatically, except that there were breakages in the REST library between versions 8 and 9 of Jira as no data is returned even when you run those two versions with same config in parallel, though that's only applicable to their self-hostable solution which is different from their cloud solution, without getting into the licensing changes in the following years.
I'm interested what you think about exact features or qualities that each has and how they compare.
