I've had the Touch Bar for as long as it's existed. It's not worth the money until external keyboards support the same feature, because anyone doing serious work on these machines is very likely to be using a desktop machine a lot of the time or have the laptop docked to a screen/keyboard/mouse/[other specialised input gear such as Wacom tablet, midi keyboard etc] at a desk. It's not worth getting used to this feature until it becomes a serious part of the workflow. I wouldn't recommend the Touch Bar yet. Still a gimmick.
I'd say the same about usb-c. It looks tidier than usb-a or a mismatched assortment of hdmi, sd, thunderbolt etc. It's about looks more than anything else. A four hole symmetrical array.
Now go get your dongles ready to fug up all of those clean lines.
