Which is more suitable, French or Spanish?

Spanish is used in: the United States in addition to Canada, the United States, Brazil, plus Spain itself, that is, Spanish-speaking countries. France: Before World War II, Spanish was widely used by immigrants (their second language) and France, as well as several nearby countries, because the usage rate far exceeded that of French. Spanish seems to be the third largest language in the world, and the first and second languages are Chinese and English. Although the usage rate of Spanish is higher than that of French, French is far ahead of Spain in economy (France and Germany control a large part of European economy). In fact, to be honest, French and Spanish are very similar, so if you master one, you can understand the other, because both come from Latin. I told you the benefits of both pronunciations, because I don't know what you really need to communicate. Although you can understand a kind of learning in general, you can't understand some! It seems that 75%+ of both sounds can be understood.
