I traded in my wife's F25 2d xDrive X3 for a 2020 X5 xDrive 2.5d and I still have my F15 2.5d sDrive

I find the F15 more responsive as it slightly lighter RWD only and has 50nm extra torque.
Comfort wise much the same even though the f15 is running on 18 inch std rims whilst the G05 is a Motor Sport with 20inch offset.
F15 uses about 6.5l/100kms and the G05 about 7.5l/100kms on the same 260km weekly trip I do.
Handling wise G05 streets ahead not quite 3 series territory but close, F15 wallows around corners in comparison.
Technology of the G05 is also way ahead as expected and I am still learning at what it has to offer 3 months after taking ownership and I have owned BMW's since 1989.
Quality wise I am not so sure there is that much difference only time will tell
