Verizon iPhone 4 vs Verizon's droid x2? Which one of these smartphone?

Which one of these smart phones is better? What are each of their pros and cons? Is the iPhone worth paying $100 more since I'm buying it from eBay?

I'm an Android guy through and through… But get the iPhone.
the X2 is still stuck on android 2.3 and won't get updated
the camera is terrible
the screen is terrible

but that is what you get from a phone that is so old… Is a year older than the iPhone 4 i think.
if you are looking for a cheaper phone, check out the Verizon Galaxy Nexus… It is a MUCH nicer phone and its still pretty cheap, up to date on android, pretty good screen and camera.
