I suppose I could answer here as I chose my current CX9 over a european...and a couple of Japanese 3 row SUV. Please forgive me if this is long winded, but it gives context to the decision making.
BACKGROUND:Came from an 2017 Acura MXD which we had gotten already up to about 60K miles on. WE needed a three row which both I could (enjoyably) drive and other members of the family including kids could drive in the near future. WE have an 8 seater already and needed a 5 flex 7 seated when in a pinch. Another consideration was availability of service in or close to our town. Acura/Lexus dealers two hours out but BMW/Mercedes/Volvo in town and Audi less than an hour away. We have two other vehicles with dealerships also two hours away, so repeated drives for service were slowly becoming a pain for me.
Off the bat already declassified Mercedes GLE 3 row (new, no history, tiny 3rd row)and X5 3 row for lack of third row space and depreciation and eventual reliability - may keep current vehicle 4-6 years.
Love the Q7, have owned 2 Audis and also seen their dark side. Enjoyed the drive of the Q7. All in all, it is ahead of the CX9, without a doubt. For the increased price however, was not worth it to me. The 3rd row is not much better than the CX9. Has more"status" , in some people's eyes but we but have no need for that currently with the other vehicles. Service distance was not an issue at less than 1 hour from home. The CX was just the better package for me at this time all things considered
Lexus RX...simply doesn't rock my boat, though statistically and truly a nice reliable, comfortable car. would have still taken one despite distance as colleagues have had their cars picked up for service locally and returned.
Volvo XC 90 - have had the yamaha sourced V8 engine and I6 both on the prior model. Never been too enamored with the current one. Drones as much if not a tad worse than the Mazda on hard acceleration, do not trust it's reliability, particularly with regards to electronics as much as the the later vehicles of the prior model range which I owned.
Acura MDX; just got out of one, current gen three. Also owned a gen 2. Good cars but I was no too thrilled with the current vehicle. Did not like the transmission, had the car suddenly go unresponsive on me on the highway while in the left lane in Chicago morning traffic and the thought of that happening to spouse/kids who might not be able to manage such an emergency turned me off. The interior was in my opinion not better than the CX9. features were comparable or less in the tech package (no rear seat heating/surround camera/ front seat cooling, heated steering)
Palisade/Telluride; too early to move me yet. I needed more reliability data as of the time of purchase, thanksgiving 2019. On paper look good. Have a truck based 8 seater already, which again reduces the need for the aforementioned.
CX9 was my final choice after the above. Might not be luxury classified vehicle but practically is pretty darned close. The interior finish is impeccable and on par with the Germans, though it may not have all the "luxury gadgets" and cachet. I love the curves of that car- can one call it a sultry looking three row? I enjoy the drive - its handling is "tight" for a three row SUV. I often forget and instinctively reach behind the steering wheel for paddles like in my daily driver...and unfortunately find none. It could readily handle 50 to 100 more horses I believe! It's not perfect, but all things considered, particularly from a driver's stand point, it's a great package and I believe it is an underappreciated gem in the US car market. Now let's hope my bet on reliability is right and I can wring 100K miles out of it
