Default MIME glass screen protector or Spigen Steinheil Ultra Crystal Clear?

Hello, I have been using a Samsung screen protector provided by a store as a gift. There are lots of fingerprints and a bit oily. In case I change a screen protector, which one do you recommend? MIME glass or Spigen Ultra Crystal?

If I get the Gumdrop Hideaway case, is it still recommended to get any of these? I read that some users removed the protector which came with the Gumdrop case due to some issues.

Thanks.
