I personally enjoy my MacBook Pro (15-inch, Late 2016) but it has a problem with going to sleep after being plugged into an external monitor all day. I find at least 1/3rd of the time it has frozen after being disconnected from the monitor and I am forced to do a hard restart. Perhaps this is user error, but I do not remember having as much issue with the older generation. I use two Dell IPS monitors which are relatively new and connect via HDMI => USB-C adapter. It's an inconvenience which you shouldn't have to deal with on several thousand dollar laptops.
