The Ordo Xenos take in Alien Weaponry, not the Adeptus Sororitas. The Sisters of Battle would probably try to burn any xeno tech they find instead of giving it to any form of tech-capable unit.

They have the same tech, in many ways the Space Marines have better. The power armor for a Space Marine is superior to a Sister since the marines armor acts like a second skin and can monitor and administer pain-relievers and such, while the Sisters armor is simply powered armor that gives them better strength. The reason only Space Marines have those huge pauldrons is because they are seated on plates that link to their eyes and move around the pauldron to not block eyesight. The Space Marines are also generally superior to almost any other soldier in the galaxy barring specialised forces like a Tyranid Carnifex, or possibly the Orks.
