Please post links if you're going to make a statement like this, especially the Pilot. FCA yes, as the ZF has been sourced out to a third party, but as ZRoger73 pointed out, the ZF for Honda is made by ZF.

Major Transmission failure
A 800+ post thread on Piloteers (which zroger73 is also engaged in) with lots of complaints (in addition to support of) the 9-speed
ZF Nine-Speed Transmission Problems, recalls and praise.
And many more.
It is also important to note that in the case of the Ridgeline we are comparing nearly 4-6 year old trucks and all of the miles they have accumulated to trucks that have been on sale for just over 2 years (most of which was during a time where people curtailed their travel) A much better look at this is on the Pilot, MDX and TLX forums where these transmissions have been in service for a lot longer.
After reading dozens of these threads over the years I've come to the conclusion you have two choices:
The 6AT, which is likely more fragile (overheating, judder etc) has drivability issues (for instance harsh shifts especially the 2-1 under deceleration) but its problems are well known (which is why I'm not linking anything, plenty of examples here), many times have simple fixes (pressure switches, shorter transmission fluid maintenance intervals), and sometimes leads to larger issues like torque converter or even entire transmission replacements (but usually with some warning).
The ZF9, which is probably stronger on the whole (especially if towing or off-roading) but is much more complex and has had most of the reason (mpg) for that complexity programmed out due to its inherent issues with smoothness (
Next-Generation Ridgeline general comments...), can have its own drivability issues with odd feeling shifts when the dog clutches are in play, clunks (
ZF Nine-Speed Transmission Problems, recalls and praise.) hesitation (
Hesitation on acceleration), erratic shifts, (
Transmission issues with the Passport Elite ) and when it does fail (many times out of the blue (
2018 EXL.....transmission failure at 5,634 miles) it almost always ends up as a full transmission replacement.
This is a lot like arguing politics. Your choice is between two turd sandwiches, so figure out which is better for you and pick your poison.
Oh, btw, the Honda 10-speed has its own issues, so the grass really isn't greener anywhere

This is my transmission failure story.... The transmission started shifting hard on November 20th, 2021 while driving 60-70 mph on the interstate. I was on a Thanksgiving trip (Indianapolis, IN to Venice, FL) with my wife and three kids ages 8, 6, and 4. We were on I-75 north of Atlanta when...
