I love both. Spanish is my native language, it's spoken in Latin America sans Brazil and even formed some creole languages in the Philippines and it's very popular in the US and is one of the six official languages of the UN and the UK department of education (or ministry, whatever they call it) said it was the most important language to learn. Spain, Mexico and Argentina are in the G20. Spanish is also the language of the media and the arts and it's beautiful all around.
French used to be really big. Today it is spoken in a lot of African countries, Quebec, New Brunswick and throughout Canada, France, Belgium, Switzerland, Luxembourg and is part of the colonial history of Indochina and Louisiana. It's still very popular in countries like Romania, Italy and the US, and is the second or third most popular foreign language almost everywhere. And it sounds wonderful and has a literary and artistic and scientific reputation that not a lot of other languages can surpass, and the diplomacy aspect of it!
