This is yet another name I disliked until fairly recently. I'm kind of drawn to the old man, vintage vibe now for some reason. The only drawback is that FranklinGraham is the most well known bearer of the name and I thoroughly dislike him.
FDR is definitely the better Franklin. I should have specified "living" Franklins. You may not be in the US? At any rate, you haven't missed much not knowing about FranklinGraham.
I also had to look up FranklinGraham! Yuck. Although my first association was Franklin the Turtle which I'm not sure is great either...BenjaminFranklin would be a nice namesake.
