Ford Kuga 2.0 TDCI or Mazda CX5 2.2 Diesel ? Durability and reliability ?

Hello together, as described above, I can not decide between the Ford Kuga and the Mazda CX5. I am looking for a used car where the car should not be older than 4 years. For me it’s mainly about which ( according to experience ) the more reliable engine has. I know that you can also have bad luck or luck with both cars, but maybe there are people here who own one of these two vehicles and could tell about how reliable or little it is reliable the car ? It MUST be a diesel because I drive about 30,000 km or more a year ( 30% city 50% highway and 20% highway ). I also like the torque of a diesel 😉 Every now and then the car has to pull a trailer 1.0 tons. And it should be an all-wheel with manual transmission. I rarely drive terrain and then only light terrain ( sometimes a gravel road or so ) About your experiences I would be very happy and would you see r grateful Lg Giusi
