I suppose the Gravel King either rolls better or is more durable...or both!(?)
It's a different sort of design.
Paselas use a thin non-tubeless road casing. If you choose the version with a protection layer, it's a sub-tread belt, intended to shield against particularly sharp objects on the road.
GK slicks use a somewhat thicker casing that makes for easy tubeless setup and should be tougher against sidewall abrasion/cuts, relevant on chunky gravel.
