I moved from 2019 X3M Comp to A 22 LCI X4M Comp and I 100% agree with your comments on both torque and handling / suspension.
I'd add that there is a subtle difference between the X3M and X4M too, with the X4M having a slightly lower centre of gravity and for me anyway less roll / weight transfer.
Really love the differences - all positive to me except in the UK we lost the ventilated seats which is annoying as I loved them.
Absolutely love your colour - probably the best I've seen on an X3M
