In all likelihood, Fran would be more efficient with Silver Eyes than Bonesword, mainly because she would be able to use them to empower her illusions. His skill only applies to plants so if he used it to do plant feats, surely he would be better than anyone (as long as the IC description met his claims), except perhaps Victoire when it comes to her roses (but is not something anyone needs to fear since she'll never get that kind of power, despite being the only Demon that actually deserves it).

After all, her focus allows her to be much better at that specific task than him. Comparable to an non specialized college graduate trying to beat a technician's focused skill. It just doesn't work that way.

Anyway, no, Fran would certainly beat BS when it comes to potential to use Silver Eyes and none of them has any potential to have Gold.
