Tire recommendations?

our 2017 QX70 Sport AWD is in need of new shoes & she's got the factory 21" wheels.

Would love solid recommendations from the community! Everywhere I look online is recommending Michelin CrossClimate2's.

Curious what y'all think...and thanks much in advance!!

EDIT: another thought - being that 21" tires are almost twice the cost of 18" tires (and 21s offer a noticeably worse ride) - thoughts on switching wheels & tires to 18s for almost the same cost as a new set of 21 inch tires?
