I also had a lot of trouble with my work-supplied 2017 MBP. I found the touchbar completely useless and never got used to it. It would randomly experience crashes or lags, a problem I never had with the old function keys when I changed the brightness, altered the keyboard backlight, or modified the volume. Even worse, the keys seemed to be laid out in a way that my touch typing couldn't adapt to -- every time I worked off of that keyboard, I would make constant typos and type significantly slower than on any other keyboard I've ever used. Switched back to a 2015 and I couldn't be happier. Battery life is better, too.
