Priority check-in actually seems to be a SkyTeam perk for Elite members (as the extra baggage allowance is), not an FB additional perk. Is this granted by all SkyTeam airlines, I'm not sure...
On the other hand, for me the main advantage FB is adding to SkyPriority is lounge access on domestic-only flights in France for Elite+ members.
