I dislike them both.
I pronounce Taurus as "tar us" and Taury as "tarry", which sounds unpleasant to me.
(I sort of like Toreador as a word name for a Taurus, though...just throwing that out there).
Most names with the Bel- prefix sound like bullies to me (because of the Latin meaning "war, fighting" and words like belligerent, bellicose).
I think a Bindi would be made fun of, so Bel or
Billie - or maybe
Linda /
Lin - would be my preference for NN.
