I’d argue PCT is one of the best synced jobs. At 50 it already has its 1-2-3, its creature canvas up to mog and the hammer combo. By 60 it already has its reversed combo and by 70 it has all its canvases (it’s only real high level skill that you noticeably feel the lack of is rainbow drip)
To me the jobs that sync the worst are VPR (below 90 it’s basically a healer for rotational complexity), RPR (you can’t build an entire job around building towards a phase you only get at level 80), DRK (level 70 ultimates are hilariously bad on DRK) and WHM (who thought that your first oGCD should be benediction and your actual gauge that makes you a useable job you get at 76)
