Weiss definatly seems like the nicer, younger sibling (just from comparing their portraits alone). Winter seems more of The Baroness to Weiss' mere Princess, but I have a feeling Winter has a soft spot for Weiss and is as friendly to her as Yang is to Ruby (I wonder if the two will bond over that).

But when it comes to running the company, I think Weiss probably trained harder (fighting a Knight), longer (since she could I would imagine), and with a more focused goal (redeeming the company and the family) than Winter could have ever hoped for, passing her along in favor of Weiss.

OR they are both heiresses and Papa Schnee hasn't decided WHO is going to inherit the company and it is still up for grabs, requiring a need to prove themselves (Winter staying home and holding down the fort and Weiss becoming a renowned huntress). Think the Succession Crisis in Fullmetal Alchemist (which I am glad I watched before learning Vic Mignogna was hired for RWBY) between the Xingese characters, who need to prove themselves so they may inherit the throne.
