both difficult^.^ , i think you should ask yourself which one your are more interested in

that's right.. it depends on yourself and people around you. for me, learning english is easier than learning spanish because i can easily find resources to learn english such as text book, audio, magazine, newspaper, songs, movies,etc. and if i want to practise my language skill, it's easier to find english speaker than spanish speaker here. so, for me, english is easier to learn than spanish. anyway, i learn spanish now. good luck for me! ^^

All languages have their difficulty ... Often depends on the person who learns. Saying whether a language is more difficult than another is a very subjective ...
