Well, at least you both like the same name! :) Explain to each other why you like it spelled the way you do. There's gotta be a reason deeper than "I just like it." Did one of you know a kid from grade school whose name was spelled the way you don't like and you didn't like that kid? Or...who knows?!
My husband wanted to give our son the middle name Von which sounds like my maiden name, Vaughan, but not my name. We squabbled about it for a few months and I finally just like, "Look, Von is not my name but Vaughan is. So if the kid's middle name is Vaughan/Von, it's gotta be Vaughan." He understood and we gave him my maiden name spelled true.
