I have the 15" with touch bar and absolutely love it - everything from the shallow keyboard to the brightness to the massive touchpad. Just perfect. The touch bar was admittedly next to useless until I ran across an app ("BetterTouchTool") that lets me customize it freely with my own shortcuts and widgets - now I actually use the touch bar multiple times a day as opposed to never.

So I wouldn't completely give up on the Touch Bar versions, especially since the 15" has a good performance bump over the 13".
