Hi,
It really depends on what do you plan on doing with the new language.
If you decide to read Spanish books or travel to Spanish, it's better to learn Spanish, vice versa, if you would like to learn more about German books and German authors, you would want to learn German and read the works in their original language, or maybe travel to Germany. (or that you have many friends or bf/gf speaking that language).
I've never learned German, but I learned some Spanish before, it wasn't very difficult, a lot of the words are very similar to English words, in fact, many words are spelled the same in both English and Spanish but only different slightly pronunciations.
Also, if you already learned some Japanese or plan on learning Japanese in the future, learning Spanish now can provide you with a very good foundation, because their alphabets pronunciations are almost identical such as the letters 'RA, in both Japanese and Spanish are pronounced as 'LA instead of RA.
Another advantage is that if you decide to learn Italian later on after learning the language of Spanish, you will find it lots easier because also, they have many similarities in phrases, sentences, spellings and pronunciations.
hope that helps.
