You left out all useful information for forming an opinion.

Where do you live? How many speakers of each language live near you?

Where do you want to visit?

What do you want to read? Don Quixote's in Spanish; Cyrano de Bergerac and The Three Musketeers are French; most opera is in Italian.

If you're interested in 16th/17th century fencing manuals, Agrippa and Capo Ferro are in Italian; Narvaez is in Spanish; Sainct Didier is in French.

I live in Texas, and Spanish is more immediately relevant. People near Quebec would have more use for French.

Languages are tools for communication and learning. Until we know who you want to communicate with or what you want to learn, we cannot advise you.
