If it's for common use, then you may not need the Touch Bar.

where the finger is pointing

Depending on ur needs actually, if u are Using the macbook for normal usage.
The non-touchbar is good enough.

But if u like the following, no harm to spend a little more for the touch bar too,
1) Touch ID - certainly a good and convenient feature for anyone, especially MacBook Pro one is 2nd gen, the same as iphone 7, fast and accurate for payment, unlocking your macbook or installing of apps or changing settings for your macbook.
2) 4 thunderbolt 3 ports - now maybe overkilled, but one cannot deny that it will make the machine more future proof.
3) 28W vs 15W Processor - The touchbar version can technically run at full speed much longer than the non-touchbar version, due to the throttling by the heat. For normal tasks, one may not be able to tell the difference this is true, but it is also something to consider. The base clock rate is higher for touchbar version explains this.
4) Touchbar - yes, it may not be perceived as essential now, but with the software upgrade and better support for third party app, this may not a bad thing to have. At least for touchbar version, one possess the full potential of the MacBook Pro comparing to the non-touchbar version, no matter u really use the touchbar or not, at least you have a choice anytime later. And the extra of touchbar is just a fraction of the total price of the macbook.
