Earlier quoted context omitted.
For whatever reason I was under the impression that those phones were larger than they are. Thanks for pointing those out to me! I'm still probably going to switch to Apple because I've been working towards being more privacy conscious in the last several months and Apple's stance on privacy and encryption is appealing.
Switching to Apple doesn't really seem like a good way to move towards being more privacy conscious. Even if you don't mind the walled garden and lack of control of your own device (you should if you really want to care about privacy), recent revelations like silently granting special permissions to Uber app should remove any remaining appeal there may have been in them.
I'd rather have a phone/OS built by a company whose primary source of revenue is not user data.
From my, admittedly limited, understanding of the issues between iOS and Android it seems like iOS is more secure/privacy oriented with some obvious caveats like the Uber app issue you mentioned.
