Well, since starting this thread, I purchased a 6S Plus off of Swappa for a pretty good price given the last experience I had messing with the 6S+ had me thinking maybe, just maybe, I could get used to it after all.
I lasted less than 48 hours. You can see in the pics I posted earlier that the 6S is kind of small in my hands. But man, I can maneuver that thing like a ninja and I like that. So, I sold the 6S Plus on Swappa and after fees and shipping I took a $20 hit which is fine.
I have accepted that whenever I see the Plus in the wild, I will appreciate it and desire it. I just have to somehow, some way remind myself that the lust will turn to irritability and I will be right back in the same spot as always. I have seen a lot of people on here say that it is impossible to one-hand a 6S. I disagree whole heartedly (not everyone has the same sized hands). I have seen a lot say that it takes about a week or two to get used to the size but that it'll definitely happen. I disagree whole heatedly on that too (that it is a given you'll get used to it)
In the end, I think the 4.7" is just a bit too small. But I find the 5.5" overall size to be just excessive enough for me to not want to deal with it 24/7.
