They have a very different style and mode of play. Playing pathfinder in shadowrun is akin to watching Godfather but it's Honk Kong Jackie Chan movie. Fun? Probably, but that's not the award winning crime drama with stellar acting and tension, same as godfather isn't a gun-ho action film with great fight coriography and slapstick humor.
Pathfinder heroic high-fantasy hack & slash action doesn't really work well with everything, certainly not with class-less grimdark cyberpunk heist, crime and shopping simulator like Shadowrun.
Another simple comparison how they heavily contradict each other. In Pathfinder half the time you are in combat, because you are good at it, while in Shadowrun, half the time you are thinking of a plan and actively trying to avoid as much combat as possible, because bullets are deadly and you ain't going to spend your nuyen on a botchy streetdoc.
