I've switched back and forth between the plus / max sized and "normal" sized iPhones a few times. I'm currently using the XS Max and have ordered the 11 Pro (non Max). In the beginning, the Plus sized phones had the better cameras and battery life so that was a reason to go with the larger version. One thing that bothered me last year was finding a case I liked for the XS Max. I like cases with kickstands and when the XS Max was released, there were more cases for the XS than the XS Max with kickstands. This year it seems to be pretty even between the two versions. I'm sure I'd be happy with either but I'm downsizing this year.
