There are definitely pros and cons to each. I have a 2018 Expedition Max that I bought new. At the time, Ford had a lot of advantages over the GMs like independent rear suspension, panoramic moonroof, 2nd row seats that slid forward/back and tipped forward with a car seat in place, 3rd row latch anchors, center headrests, and higher safety and tow ratings. The 2021+ GMs caught up on several things, and they offer extras like a head-up display and air suspension.
I've loved my Expedition, but it's had a ton of problems: cam phasers x2, turbo wastegate rattle, leaking rear differential, transmission slipping into neutral while driving, sunroof, 6 blown factory shocks, bad ignition coil, faulty horn, etc. I started thinking about replacing it and rented a Yukon XL on Turo. It overall package really impressed me. We have a travel trailer and I like the suspension options on the Yukon (magnetic shocks plus air springs). The family loved it and we ordered one, which I'm excited to get early next year (currently at status 3300).
2018 was the first year of the current gen Expedition, so a lot of my issues have been fixed in the newer models. I'm hoping the Yukon is more reliable for me. On a side note, before moving to full-sized SUVs for the family I was a BMWCCA member and did a few HPDEs at VIR. Great times. Thankfully I didn't blow an engine; that's no fun!
