I feel that, despite their variances, BT and SW are just are much SM as BA and DA. When I think "Spaces Marines", I think the Loyal 1st Founding, Successors, and following Loyalist Foundings. Though GK and SoB are Imperials in Power Armor, their purpose, structure and deployments are too much different, in-game and fluffwise, to be considered Space Marines. Plus SoBs have vaginas, duh!

Edit: And based on how kick ass GK actually are, they have functioning dangly parts because they frequently f*ck up daemons. In conclusion, GK and SoB could not be considered "Space Marines" based solely on the fact that they are not neutered. jk

They undergo much more severe psy conditioning, and (if GK fluff is true) their gene-seed is taken from the Emperor or similarly pure source, as opposed to Space Marines which derive from a Primarch source. SoB undergo similar surgeries and enhancemets with the exception of the black carapace and gene-seed. Battle Sisters are Battle Sisters as Grey Knights are Grey Knights. Just as it is NOT the equipment that makes a Space Marine (power armor and bolters), it is NOT the surgery. It is the dogma, organization and operation of the force, in a fluff sense. Huuurrr!
