Completely depends on the job. On something like DRG you pretty much can't do anything other than doing a lot of damage. In which case carrying JP DF is actually more impressive because they suck at doing damage compared to NA PF, often using incredibly horrible downtime strats (which the devs have slowly neutered by making hitboxes big and uptime strats easy to achieve, however).
On something like SCH, it's probably more impressive to carry NA because people suck at mechanics generally.
Ultimately the difference is so minor it doesn't really matter.
