i think if you don't wear any YG, you should probably get the single motif in WG. it's a great everyday pendant and would coordinate with all your other jewelry nicely! but if you decide to add YG jewelry to your collection, YG MOP is my favorite combination!
I might have to break my WG preference! I never really liked YG before, because I was used to lower-end quality gold... When I bought my SO his YG Cartier Love bracelet, I marveled at the luminous quality of the yellow gold! He bought me the WG Love, because I am NEVER taking this baby off, so it was the wiser choice.
But... I dunno. The MOP seems to go better with the YG.
