I'm not going to "stan" for JIRA, but I've developed software before Jira with Bugzilla and other smorgasborgs of tools.
JIRA was a dramatic improvement at one point, however, it is bought and sold to managers, so it is unsurprising it eventually converges to managerial overengineering.
I've seen many small orgs adopt trello, slack, discord and other tools organically. I've rarely seen a small org willingly choose jira or teams; that is a choice that is almost always imposed by non-users of those tools.
