What is the most reliable engine option for the Ford Galaxy?

I am planning on purchasing a Ford Galaxy and I am wondering which engine option would be the most reliable in terms of maintenance and longevity. Any advice would be greatly appreciated.

I would highly recommend the 2.0L EcoBoost engine, it has proven to be very reliable and efficient.

I have had great experience with the 2.0L TDCi engine, it's a diesel option but it's very strong and fuel efficient.

I've owned a Ford Galaxy with the 1.5L EcoBoost engine and it has been very reliable for me.
