[Fallout] Why does the East Coast BoS use inferior T45-d power armor when the West Coast BoS uses T51-b power armor?

Power armor is rare. You use all the suits you have. After all, both are WAY superior to a combat armor.

The Brotherhood of Steel is based out of the ~~East Coast~~ West Coast, so they usually get all the fancy stuff. the far-off chapters have to make do with the remains.

Edit: Mixed up stuff.
