The ZF 9 speed was launched with a lot problems and perhaps should have been delayed. I wouldn't form an opinion on the Ford and GM 9 and 10 speeds based on your Chrysler/ZF 9 speed experience.
ZF has issued an recall for 505,000 nine speeds due to them dropping unexpectedly into neutral. The issue was/is a bad crimp on a wiring harness attached to the sensor cluster.
They also have had two or three flashes for shift adjustment do to customers complaining of their cars hunting for gears. GM and Ford are going to have the same issues as they transition those ten speeds into their product lines. Heck the nine speed won't hit and hold the upper gear until 72 mph what do you think the chances that a ten speed would be any better?

The nine-speeds had numerous teething problems (that were not unique to Chrysler). The company noted that the 2016 model year had many improvements; the company did not reveal what they were, but it seems to be a combination of hardware and software. There were numerous software updates, the final major ones likely being issued in April and May 2016, covering low speed drivability and upshift and downshift quality. These updates are said to greatly improve transmission performance, and seem to resolve most outstanding software issues.
Some reported rough shifting after work was done on their car, which may indicate a missed step in the repair: skipping the “PROXI alignment,” which updates information in all the car’s systems. Even a TCM update may require PROXI alignment. A technician wrote, “PROXI alignment is required when a module is replaced, or, in this case, the transmission bangs into gear something fierce. It does make a big difference.” One telltale (though it may not always appear) is a blinking odometer.
An FCA spokesman wrote, “It's called out in the service instructions. Skipping the procedure is not an option. We encourage customers to contact the company directly if they have concerns, at 1-877-IAM-JEEP (426-5337); 1-888-CIAO-FIAT (242-6342); or 1-800-CHRYSLER (247-9753).”
