I've been torn between which model to get so I've narrowed the deciding factor down to the camera. Obviously the OIS on the Plus will give it a slight advantage over the 6s, but if there isn't a dramatic difference I would go with the smaller iphone. Anyway, all of the online/youtube reviews I've seen only compare the new models against the old ones or competing android devices. This is the first review I've watched that directly compares the 6s and 6s plus camera. Skip to the 9:00 minute unless you want to watch the whole review.
