Mob taking Reigen as last name, because the sound of it means so much to them both after years of adressing his soon-to-be husband with that name.
Mob taking Reigen as last name to put the family part into Arataka's family name.
vs
Arataka taking Kageyama as last name, because Mob's family is important to Mob while the only importance the name Reigen has for Arataka is that Mob adressed him as such for years.
Arataka taking Kageyama as last name because Mob wants him to become part of the Kageyama family.
(it's a draw)
