I’m not sure what “the usual complaint” about Jira is. It sounds like you perceive the usual complaint to be about feature bloat. You only briefly mention speed, which is the only complaint I had about using Jira as an IC developer. From the perspective of an IC I think all these systems are incredibly similar. Jira is the only one that was, very simply, ridiculously slow. As in 5-10 seconds to load any page.
