I have tiny hands, so I decided the 7+ is just gonna be irritating as hell. As for the GB, I have a 32gb now (albeit with an SD card but that doesn't get used). I'm not even anywhere close to filling it up because all my photos are stored in various clouds- as well as backed up onto my hard drive. Storage isn't really an issue for me - I'm not willing to pay more for extra storage when there are ways around it. As for the camera, I genuinely don't care that much as long as it takes a nice clear image. I have a couple DSLR cameras at home for proper photography.
So I ordered the iPhone 7 32gb
