I'd say that Byakugan is more of a tool than a Sharingan not on its own, but combined with Hyuga ability to release chakra from all the tenketsu of their body, which isn't really an ability coming from Byakugan itself, rather a separate one. It's just that all the Hyuga have both this ability and Byakugan by default which allows them to use these in combination permanently.
