Been testing side-by-side the tb model and non-tb for a week.
Touch bar specs:
3.3i7, 16GB RAM, 512SSD (Silver)
Non-Tb specs:
2.4i7, 16GB RAM, 512SSD (Gray)
Interestingly enough, I've found that the performance of the 2.4 i7 in the non-tb and the 3.3 i7 in the tb to be within 4-5% of each other in Geekbench.
Aside from that, the battery life has been between 8-10 hours on non-tb and 4-6 hours in tb. Usage includes a bit of pycharm/xcode, terminal, spotify, messages, mail, safari, and sublime text.
The non-tb runs WAY cooler than the tb. If you flip them over, you'll actually see that there are no vents on the undersides of the non-tb - guess that's the advantage of a 15W cpu.
Under sustained loads (20m+ of hitting it hard), the tb holds up a little better than the non-tb. Most of my high-load scenarios are bursty - build/compile in IDEs and very occasional work in Adobe CS.
I tried to get used to the touch bar, but just couldn't since my hands are totally mapped to function keys. It also feels odd to do keyboard shortcuts involving function + keyboard keys.
As far as how useful the touch bar is to you - ymmv. Really depends on which apps and which types of apps you use - I can see the value in video/audio/design/engineering apps that require precise control of sliders. (Also worth noting that the Mac trackpad has been precise for a long time, and much bigger now!)
The touch bar version totally wins on I/O. Not just having 2 more ports, but being able to choose which side of the machine you want to connect to peripherals is way more convenient.
I was able to get both machines to drive 2x ASUS 1080p displays, connect to my USB3 hub, and charge my machine(s) with just 2 cables (one USB-C to HDMI I got for cheap on Amazon and one USB-C Multiport from Apple)
I have owned both for a week now and I'm going to return the tb. The battery life and familiarity with the function keys made the decision for me. In my opinion, the maxed-out non-tb is the closest successor to last year's 13 inch with 3.1i7 - great performance and great all-day battery life.
If the touch bar model was noticeably faster for my use case or if I needed 4 USB-C ports, I would have definitely considered the upgrade and taken the hit in battery life.
But to each, his own
