I've used Jira (last job) and Linear (now). I don't really see any compelling reason that Linear is "better" than Jira. Jira was always pretty easy to use and navigate for me, and we had team-focused views for ourselves.

Even on this site, several opinions I looked at are about the idea of process or the implementation of a process—not really about Jira. And several of the ones about Jira just came off as whiny nitpicking and not actually meaningful.
