What language is harder Spanish or French?

Many people agree that French is a harder language to learn than Spanish, but French grammar more closely mirrors English grammar than Spanish grammar does.

It is far better, if you have to choose between studying French or Spanish that you choose the language that is more useful to you since the level of difficulty of both languages (assuming you know English) is roughly equivalent. For example, we are not contrasting Spanish and Arabic where Arabic is significantly harder to learn than Spanish.
