You have fewer problems with Jira. You’re still paying more for a slower application with a clumsy UI.
I also wouldn’t be so quick to condemn the PM. I’ve seen plenty of developers insist on complex workflows and custom fields because they think they can automate everything, only later to realize they’ve created a second job. The problem is basically the lack of a functioning feedback mechanism to ask “do we need this enough to pay for its care and feeding?”, and I’ve seen people from every role on either side of that, although it’s certainly more common to see business people underestimate the complexity of what they’re asking for.
