Citizens are mostly unconditional, so yes, Swedish citizenship are more permanent. There is discussion around revoking membership from people with double memberships, but it is in legal limbo since it may not be consistent with the constitution.

Permanent Residency were not removed if you moved away. It was also not removed if a person did criminal activity. There was a bit weird middle ground where people retained their permanent residency status, but was expelled from the country due to serious crime.
