Honestly, I'm not keen on any of the Romance languages. I prefer Germanic and central Semitic languages.
Spanish is basically corrupt vulgar Latin.
I'm less informed of the origins of French, but the pronunciation is very weird.
(Granted, English and German are corrupt proto west Germanic, or even proto Germanic, but we don't have a good understanding of what that was, unlike classical Latin.)
I have some interest in French because of the strong influence Norman had on the English language starting in 1066. However, I prefer the Germanic component in English. I somewhat resent the Norman/French influence for badly corrupting English, particularly English spelling. Several of my friends are learning French.
Spanish would be very useful and practical. It's one of the world's top three languages, and is a major language here in South Texas. About a third of the local digital terrestrial broadcast television channels are in Spanish. My mom's native language is Spanish.
