What are the big differences between European Spanish and Latin-American Spanish?

After i finish Italian, i would like to learn another language, out of interest and because it would look good on my resume. I now speak Dutch, German, English, French, Latin and Italian and i'd like to learn Spanish next. But they gave 2 options, European or Latin-American.

What are the big differences? Are they real big? Will i be able to understand the one if i speak the other and will other people? Which would you choose and why?
Sorry i forgot to say i know Japanese too. But i'm really not interested in Chinese or Arab. As i said i also learn languages out of interest, for the cultures and books and really, for me, Europe's renaissance and that literature are my interest. I learned Japanese when i still did martial arts such as jui-jitsu.

Why do Americans see every Hispanic person as a Mexican?

It doesn't matter where they are from, they (not including hispanic americans) always ask them if they are mexican or what part of Mexico they're from. Now, if they tell them first " I'm from-------" some of them will actually say: So, what part of Mexico is that at? Or Do you speak puerto rican, mexican, etc.?
Now remember, this also includes Americans stationed or living abroad in Europe. Some visit Spain are kinda shocked that spanish is spoken their. And still they ask hispanics there if they are Mexican.

Would you make a fair comment about Brazilian Portuguese & Spanish (European + Latin American)?

In Europe, Spanish is absolutely in a stronger position than Portuguese. In USA, the most popular foreign language is latin-american Spanish, especially Mexican style, because there're a lot of Mexico immigrants in USA. & In latin-america, people speak latin-american Spanish, it mainly includes Mexican, Argentine, Chilian style, & In Brazil, people speak Brazilian Portuguese, which sounds softer & more nasal than Spanish, & it shows some similarities to that of French. Brazil's been working to develop its economy and resolve societal problems, Brazil is the largest and most populous country in South America, the fifth largest country by geographical area, & its population comprises the majority of the world's Portuguese speakers. Brazil is the largest national economy in Latin America, the world's tenth largest economy at market exchange rates & the ninth largest in purchasing power parity. If you had to choose between Brazilian Portuguese & Spanish, which would you prefer to learn?

Mexicans don’t speak two languages only as most people think?

If they reside in the United States then they most likely speak three languages. English, Spanish and Nahuatl. Most Mexicans don't know that when they speak Spanish they are actually using a lot of vocabulary from the so called Aztec language. As many of you may know. Mexicans are basically a combination of the l Aztec Warrior and the Imperialist Spaniard from Europe. They use a lot of words from the Nahuatl language and dont even realize it. Mexicans speak a hybrid of the Nahuatl language and Spanish. Now three with English haha.
