Well, they were pretty much the same in the eyes of Catherine (and Fritz). Needless to say that the OTL criteria proved to be far from optimal: in her desire to get a complete puppet Catherine ended up with a powerless candidate who kept causing problems. Well, while Catherine was definitely quite intelligent, her judgement of the people was not always perfect and superficial “brilliance” of her reign was camouflaging a lot of serious problems. It is not a big surprise that Paul initially was greeted by “everybody” as someone willing to start fighting corruption and wastefulness of the previous reign.I didn't deny it. I selected all the "pluses" of Czartoryski as a things which could block him road to the throne in the eyes of Peter and Fritz.
