I like all
Claire variants. I think
Claire itself looks solid, yet light and classy.
My daughter (
Clarisse) prefers to go by
Clare than
Clarisse, and I only spell it
Clare for continuity to the spelling of her actual name. Had I named her
Clare... I would have spelled it
Claire.
While I don't find
Claire boring, I will say that I prefer
Clarisse or
Clarice myself. Clarion I prefer over all.
