Funny that you mention English as better for cursing; as a French, I've always found the English catalogue of dirty words and insults quite limited. There doesn't even seem to have more than 2 or 3 common names for genitals of both sex, or even several dirty names for sodomy. Imaginative genitals naming coupled with religion, dirty things and weird sexual practices allow for some nice compositions :)
Well, I have to admit my knowledge of French is limited to a handful of words. The only languages I know well enough to make a comparison are German and English. :-/
