One issue is that many many ticket management solutions suck a lot more that JIRA.
As an analogy, it feels the same as saying "git sucks", and going on a journey to try CVS, SVN, VSS, DropBox's version management, Apple's TimeMachine, Synology's file management etc. to discover the strength and weakness of these random solutions one by one.
At the end of the day you end up really liking git, but when telling to people that git is really great you're met with grunts and middle fingers.
i mean, i never said jira was good. i said that it was not as bad as azdo.
after 17 years working as a dev, i came to the conclusion there's no good ticketing system, there's only less-bad-ones. and i honestly think a well configured jira instance is the pile-o'-shit king.
CVS isn't good because Visual Source Safe exists.
