Living in East Java vs West java! Need advice!

This coming July, I plan on moving to Indonesia until the end of the year. I have the options to go for Malang or Sukabumi. I wanted to know anyone's opinon on these two islands. I plan to travel after my contract is up, and surrounding conveniences should be taken into consideration, but not as much as the local setting. I am looking for mountains, scenery, and maybe some surfing or fun night life. anything would help, though! (And possibly a larger volume of english speaking, though I am learning Bahasa now)
