I popped in a Samsung shop the other day to pre order, and couldn't decide which size I preferred, and was stood, holding one of each for 20 mins, debating, and throwing the pros and cons round in my mind, until one of the shop workers showed me their S9+ in its case, and it was huge. I didn't consider the case adding size to it, and it made my decision for me. The S9 feels very comfortable for one handed use, too, so I swerved the plus, and stuck with the S9. I honestly can't see the extras in the plus making a big difference, or making me able to accept the phone bulging out my jeans pocket
