I also just made the jump to the new MBP, and wasn't too enthusiastic about the touch bar, but I've come to like it for when I can really use it. It is still a bit gimmicky, but it has practical use in some apps that actually use it, like Spotify, Sketch, Photoshop, etc. Having a dedicated hotkey to functionality I use frequently is very helpful at times.
Two rage inducing things though. I realize how often I rest my fingers on the escape key... Took me a while to break that habit. Next, when I have Chrome open, I'm always hitting the back button randomly. I can customize this though so there isn't a button in that spot I hit often, just haven't gotten around to it.
Over all, I think it has some minor practicalities, but it's not a huge selling point IMO.
